The purpose of this research is to examine how visual communication can be interpreted in different ways and even in opposition to the creator’s intention, and to understand how different visual signs in images convey meaning to explain audience’s oppositional reading. Through a qualitative methodological approach, a semiotic comparative analysis of two covers of the fashion magazine Vogue featuring Kamala Harris will be carried out, a digital cover and a print cover. Theoretically, the analysis is grounded in postcolonialism, representation, and Stuart Hall’s encoding and decoding model of communication. The results suggest that there are signs in the photograph on Vogue’s print cover that can be interpreted from a postcolonial perspective, and both oppositional and preferred readings are discussed.

Psychopathy, as conceptualized by Cleckley (1941), describes a constellation of psychological and behavioral correlates including superficial charm, untruthfulness, lack of remorse or shame, poor judgment, and failure to learn from experience. Based on Cleckley's initial work, Hare (1991) developed a two-factor model of psychopathy. The purpose of this study was to investigate the roles that sensation seeking, impulsivity, ADHD, conduct disorder, and oppositional defiant disorder have on adolescents classified as psychopaths. The participants consisted of 79 adjudicated male adolescents in a maximum-security facility. As hypothesized, adolescent male psychopaths had higher levels of sensation seeking, impulsivity, conduct disorder and oppositional defiant disorder. A discriminant function analysis found that sensation seeking, impulsivity, ADHD, Conduct Disorder, and Oppositional Defiant Disorder was moderately useful in classifying adolescent psychopathy. The results suggest that behavioral dysregulation is an important aspect of adolescent psychopathy. The relationship of these data to theories of adolescent psychopathy is discussed.

O comportamento opositor é frequente na infância e está associado a sintomas internalizantes e externalizantes, podendo causar prejuízos na adolescência e na vida adulta. Estudos recentes apontam que o comportamento opositor abrange três dimensões com comorbidades e valores preditivos particulares, como irritabilidade, oposição e ofensiva. Também sugerem que tanto a hiporresponsividade quanto a hiper-responsividade cutânea simpática estão associadas a algum comportamento agressivo e/ou antissocial. A essa responsividade dá-se o nome de arousal. A hipótese deste estudo é de que as diferentes dimensões do comportamento de oposição estão associadas a níveis aumentados de arousal. O objetivo do trabalho foi verificar a associação entre as dimensões do comportamento de oposição e os níveis de arousal em adolescentes. Além disso, pretendeu-se verificar a relação entre os comportamentos específicos, como agressão verbal, física ou social, e os níveis de arousal e a associação entre a trajetória e o número necessário de estímulo aversivo até a habituação com as diferentes dimensões de oposição. Trata-se de um estudo transversal com adolescentes de escolas públicas da área de abrangência do Hospital de Clínicas de Porto Alegre (HCPA). Para avaliar o comportamento opositor e suas dimensões, utilizou-se a escala Youth Self Report. Para avaliar o comportamento agressivo, utilizou-se a versão brasileira modificada do Olweus Bully/Victim Questionnaire. O arousal foi avaliado por meio da resposta cutânea simpática (RCS). Para investigar a RCS, aplicaram-se 10 estímulos aversivos nos adolescentes e mediuse a amplitude de cada resposta gerada. A associação entre comportamento de oposição (variável dependente) e arousal (variável independente) foi investigada por meio de um modelo geral linear, enquanto as análises exploratórias foram avaliadas por meio de correlação linear e análises repetidas de covariância. Este estudo foi aprovado pelo Comitê de Ética do HCPA. Um total de 38 estudantes com média idade de 13,83 (DP=1,46) anos foram incluídos no estudo. A RCS aumentada esteve associada ao comportamento de oposição [Pillai’s Trace=0,234; F(2,33)=5,037; p=0,012; Xp 2=0,234], e as meninas apresentam maiores níveis de comportamento de oposição [Pillai’s Trace=0,219; F(2,33)=4,637; p=0,017; Xp 2=0,219]. Entretanto, tal associação foi específica para as dimensões de oposição e ofensiva [F(1,34)=7,802; p=0,009; Xp 2=0,187]. Não houve associação entre níveis de arousal e idade. As análises exploratórias revelaram que a RCS aumentada está associada a diversos tipos de comportamento de oposição e ofensivo relacionados ao comportamento agressivo [Pillai’s Trace=0,487; F(3,29)=9,189; p<0,001; Xp 2=0,487] e que apenas o primeiro estímulo aversivo foi responsável pela diferença entre adolescentes com níveis maiores e menores de comportamento opositor [F(9,197)=2,548; p=0,008]. Não se observou diferença significativa entre esses grupos e o número de estímulo até habituação. Este foi o primeiro estudo a investigar os aspectos psicofisiológicos de comportamento de oposição por meio da RCS em adolescentes. Os resultados confirmam a hipótese de que a resposta autonômica simpática pode variar de acordo com as dimensões de comportamento de oposição. Apesar das limitações do estudo, os achados auxiliam na validação das distintas dimensões do comportamento de oposição. / Oppositional behaviors during childhood are common, and are associated with symptoms of internalizing and externalizing. Oppositionality can negatively affect adolescence and adult life. Recent studies have shown that oppositionality encompasses three distinct dimensions with different predictive values of comorbidity: irritable, headstrong, and hurtful. Other studies suggest that both increased and reduced sympathetic skin response (SSR) are linked to antisocial and/or aggressive behavior. This response is called arousal. Our hypothesis is that the oppositionality dimensions are associated with increased levels of arousal. We aimed to examine the relationship between oppositional behavior dimensions and arousal levels in an adolescent sample. In addition, we studied the correlation between specific aggressive behavior, such as verbal, physical or social aggression and arousal levels. We also identified the link between the trajectory and number of aversive stimuli necessary for habituation to different oppositional dimensions. This is a cross-sectional study encompassing teenage students from public schools in the Hospital de Clínicas de Porto Alegre (HCPA) coverage area. Oppositionality and its dimensions were assessed with the Youth Self Report scale and aggressive behavior was evaluated with the Brazilian modified version of Olweus Bully/Victim Questionnaire. Arousability was assessed through SSR at the neurology department at HCPA. To assess SSR, we delivered 10 aversive stimuli to adolescents and measured the amplitude of each SSR generated. The association between oppositionality (dependent variable) and arousal (independent variable) was analyzed using general linear models and the exploratory analyses were studied with linear correlations and repeated covariance analyses. This study was approved by HCPA’s ethical committee. A total of 38 students with an average age of 13.84 (SD= 1.46) years were included in the study. Increased SSR was linked with oppositional behavior [Pillai’s Trace=0.234; F(2.33)=5.037; p=0.012; Xp 2 = 0.234] and girls showed higher levels of oppositional behavior [Pillai’s Trace=0.219; F(2.33)=4.637; p=0.017; Xp 2= .219]. However, this correlation is specific to headstrong/ hurtful dimensions [F(1.34)=7.802; p=0.009; Xp 2 0.187]. There was no link between arousal and age. The exploratory analyses showed that increased SSR is associated with several types of headstrong/hurtful behaviors related to bullying [Pillai’s Trace=0.487; F(3.29)=9.189; p<0.001; Xp 2=0.487] and only the first aversive stimulus was responsible for the difference between adolescents with high and low oppositional behavior scores [F(9.197)=2.548; p=0.008]. There were no differences between these groups in terms of the number of stimulinecessary for habituation. This is the first study to examine the psychophysiological aspects of oppositional behaviors in an adolescent community sample using SSR. The results confirm our hypothesis that sympathetic autonomic response can vary based on types of oppositional behavior. Despite our limitations, the results help validate the different dimensions of oppositionality and indicate that oppositional behaviors are modulated by both environmental and biological factors.

<p>Za poremećaje iz grupe koja je u DSM-IV označena pod nazivom Deficit pažnje i poremećaji sa nasilničkim pona&scaron;anjem, a to su Deficit pažnje/Hiperaktivni poremećaj (ADHD), Poremećaj u vidu protivljenja i prkosa (ODD) i Poremećaj pona&scaron;anja (CD), može se reći da kao jedno od svojih osnovnih obeležja imaju i međusobni komorbiditet. I istraživačka praksa i iskustva kliničara ukazuju na to da je za ova tri poremećaja karakteristična tendencija da se javljaju mnogo če&scaron;će u kombinaciji, nego kao zasebni psihopatolo&scaron;ki entiteti.<br />Imajući u vidu čest komorbiditet, a uzimajući u obzir i činjenicu da među autoritetima na području bavljenja problematikom vezanom za poremećaje iz ove grupe ne postoji saglasnost po pitanju međusobnog odnosa ova tri poremećaja (ni u poslednjim izdanjima DSM i ICD klasifikacionih sistema ovi poremećaji ne tretiraju se na isti način), ovim istraživanjem nastojalo se utvrditi u kojoj meri su ADHD, ODD i CD zaista tri jedinstvena i nezavisna složaja pona&scaron;anja, ili se pre mogu tretirati kao jedan op&scaron;tiji psihopatolo&scaron;ki fenomen.<br />Na uzorku od 1471 deteta dve uzrasne kategorije, a prosečnog uzrasta od 9 godina i 4 meseca, primenjene su skale procene prisustva pona&scaron;anja karakterističnih za ADHD, Poremećaj u vidu protivljenja i prkosa i Poremećaj pona&scaron;anja. Skale su popunjavali učitelji dece. Od instrumenata je kori&scaron;ćena i skraćena forma treće revizije Konersove skale koju su popunjavali i učitelji, ali i deca iz starije grupe (sve tri skale kori&scaron;ćene u istraživanju visoke su kriterijumske validnosti). Na osnovu pravila za skorovanje, izdvojena je grupa od 373 dece koja manifestuju bihevioralne indikatore nekog od tri navedena psihopatolo&scaron;ka fenomena ili vi&scaron;e njih istovremeno. Na osnovu analize međusobnih preklapanja ispitivanih entiteta, može se zaključiti da je deficit pažnje, posmatran kao zasebna dimenzija, najmanje komorbidan od svih ispitivanih fenomena. Hiperaktivnost, posmatrana samostalno ili u kombinaciji sa deficitom pažnje, mnogo vi&scaron;e je povezana sa ostalim problemima, nego &scaron;to je to deficit pažnje. Poremećaj pona&scaron;anja i Poremećaj u vidu protivljenja i prkosa gotovo su uvek povezani, ili međusobno ili sa kombinovanim ADHD podtipom, odnosno sa izdvojenom dimenzijom hiperaktivnosti.<br />Rezultati konfirmatorne faktorske analize pokazali su da je model sa najboljim indeksima podesnosti bifaktorski model sa 4 faktora (deficit pažnje, hiperaktivnost, prkosno i suprotstavljajuće pona&scaron;anje i problemi u pona&scaron;anju), &scaron;to bi značilo da četiri izdvojena faktora predstavljaju fenomene koje karakteri&scaron;u pona&scaron;anja specifična za svaki od njih posebno, ali su ta pona&scaron;anja istovremeno i zajednički indikatori jednog generalnog faktora. Hiperaktivnost je u najvećoj meri zajednički fenomen sva tri poremećaja koja su predmet proučavanja u ovom radu, dok je nepažnja u najmanjoj meri zajednička svim poremećajima. U daljem toku statističke obrade podataka, primenjena je analiza latentnih profila. Rezultati ove analize saglasni su sa rezultatima dobijenim na osnovu analize komorbidnih stanja, kao i sa rezultatima konfirmatorne faktorske analize. Deficit pažnje, hiperaktivnost, prkosno i suprotstavljajuće pona&scaron;anje i problemi u pona&scaron;anju predstavljaju bihevioralne dimenzije koje su često povezane, pri čemu je komorbiditet svih navedenih problema zajedno posebno čest, kao i kombinacija hiperaktivnosti i deficita pažnje. Na osnovu svih sprovedenih analiza nameće se zaključak da ADHD, ODD i Poremećaj pona&scaron;anja pre predstavljaju različite dimenzije jednog generalnog psihopatolo&scaron;kog fenomena, nego &scaron;to ih možemo posmatrati kao entitete potpuno nezavisne jedan od drugog.<br />Suprotno postavljenoj hipotezi, uzrast se nije pokazao kao značajan faktor za manifestovanje pona&scaron;anja koja su tipična za Poremećaj u vidu protivljenja i prkosa i Poremećaj pona&scaron;anja. Potvrđena je pretpostavka o tome da deficit pažnje tokom vremena perzistira kod dece i ispoljava se u istoj meri, ali ne i pretpostavka o tome da dolazi do redukcije motornog nemira kako dete biva starije. Deca sa pona&scaron;anjima koja karakteri&scaron;u svaki od tri poremećaja imaju značajno slabije &scaron;kolsko postignuće u odnosu na kontrolnu grupu dece, pri čemu je saznanje o &scaron;kolskom uspehu deteta značajnije povezano sa učiteljskom procenom pona&scaron;anja dece nego sa samoprocenom samih učenika. Gradska sredina pokazala se kao značajan faktor za manifestovanje pona&scaron;anja karakterističnih samo za kombinovani ADHD podtip. Kao varijabla od značaja za ispoljavanje problematičnih pona&scaron;anja, pokazao se obrazovni nivo roditelja, i oca i majke. &Scaron;to su roditelji vi&scaron;eg obrazovnog nivoa, deca u manjoj meri manifestuju pona&scaron;anja koja su tipična za neki od tri poremećaja.<br />Rezultati dobijeni ovim istraživanjem jasno ukazuju na neophodnost posmatranja tri poremećaja iz grupe Deficit pažnje i poremećaji sa nasilničkim pona&scaron;anjem kroz drugačiju prizmu, a ne samo uzimajući u obzir kategorijalni pristup. U daljim istraživanjima problematike deficita pažnje i poremećaja sa nasilničkim pona&scaron;anjem u na&scaron;oj sredini, bilo bi poželjno uzorkom obuhvatiti decu iz vi&scaron;e od dve uzrasne kategorije, kao i decu iz velikih gradova, a svakako da bi uključivanje kliničkog uzorka dece u značajnoj meri doprinelo daljem rasvetljavanju međusobnog odnosa ADHD-a, Poremećaja u vidu protivljenja i prkosa i Poremećaja pona&scaron;anja.</p> / <p>One of the main features for the DSM-IV Attention Deficit and Disruptive Behavior Disorders (Attention Deficit/Hyperactivity Disorder, Conduct Disorder and Oppositional Defiant Disorder) is their mutual comorbidity. Both research and clinical practice showed that ADHD, ODD and CD typically occur in combination and that noncomorbid ODD, ADHD or CD are fairly rare. The overlap between those diagnosis is very well established. Regarding the frequent comorbidity, together with the fact that there is no consensus among authorities in the field (the specific criteria for diagnosing ADHD, ODD or CD vary between the guidelines adopted in the United States &ndash; DSM, and those used in Europe and in other international communities - ICD), one of the aims of this study was to determine whether ADHD, ODD and CD are really three unique and independent behavioral psychopathological entities, or those three can be treated as one more general psychopathological phenomenon.<br />The research was conducted on a convenience sample of N=1471 children (N=760 boys), with an average age of 9 years and 4 months. The presence of characteristics of ADHD, Oppositional Defiant Disorder and Conduct Disorder was measured with three scales &ndash; IVJER, CDRS-IV and ODDRS. These scales have been administrated to teachers. Third revision of the Conners Rating Scale (CRS) was also used in this study &ndash; both teacher report short form and self-report short form. Based on the rules for scoring the rating scales used in this research, a group of 373 children, who exhibit behavioral indicators of one of the three psychopathological phenomena listed above or several of them simultaneously are identified. On the basis of an analysis of the mutual overlapping of the examined entities, it can be concluded that the attention deficit, observed as a separate dimension, is the least comorbid of all the investigated phenomena. Hyperactivity, observed alone or in combination with attention deficit, is much more associate with other problems than attention deficit alone. Conduct Disorder and Oppositional Defiant Disorder are almost always in correlation, either with each other or with a combined ADHD subtype, or with a separate dimension of hyperactivity.<br />The results of the Confirmatory Factor Analysis (CFA) showed that the model with the best goodness-of-fit indices is the bifactor model with 4 factors (attention deficit, hyperactivity, defiant and oppositional behaviors and behavioral problems), which means that four separate factors represent phenomena which are characterized by behaviors specific to each of the factors, but, at the same time, these behaviors are the common indicators of the general factor. Hyperactivity is largely a common characteristic of all three disorders from the group, while attention deficit is at least common to all disorders. The results of the Latent Class Analysis (LCA) are consistent with the results obtained from the analysis of the mutual overlapping of the examined entities, as well as with the CFA results. Attention deficit, hyperactivity, defiant and oppositional behaviors and severe conduct problems are behavioral dimensions which are often in correlation, with the comorbidity of all these problems together being particularly common, along with the combination of hyperactivity and attention deficit. The research findings showed that ADHD, ODD and Conduct Disorder are more likeley to represent the different dimensions of a general psychopathological phenomenon, than being the entities completely independent of each other.<br />In contrast to the hypothesis, age did not prove to be a significant factor in the manifestation of behavior that is typical of Oppositional Defiant Disorder and Conduct Disorder. It is confirmed that attention deficit persists over time in children and is demonstrated to the same extent, but it is not confirmed that there is a reduction in hyperactivity as the child gets older. Children with behaviors that characterize each of the three disorders have significantly lower school achievement than the control group of children, whereby the knowledge about the child&rsquo;s school achievement is significantly more associate with the teacher&#39;s assessment of the child&rsquo;s behavior rather than with the self-evaluation of the students themselves. The urban environment proved to be a significant factor in the manifestation of behavior typical only of the combined ADHD subtype. As a variable of significance for the manifestation of problematic behaviors, the educational level of parents has been demonstrated. It is less likely for children to manifest behaviors that are typical of one of the three disorders, if the parents&rsquo; educational level is higher.<br />The research findings clearly point to the necessity of observing three disorders from the group Attention Deficit and Disruptive Behavior Disorders through a different prism, not just taking into account the categorical approach. The further research in the field of problem behaviors in our community, should include children from more than two age categories, as well as children from large cities. Clinical samples of children will significantly contribute to further clarification of the relation between ADHD, ODD and Conduct Disorder.</p>

This study aimed to examine the association between specific maternal characteristics (i.e., parents&rsquo / personality, depression, anxiety, affective state, and coping strategies) and childhood ADHD, Oppositional Defiant Disorder (ODD), and Conduct Disorder (CD) symptoms in children with and without the diagnosis of ADHD. Method: Data was obtained from 231 subjects including mothers of 77 children who were just diagnosed by Child Mental Health Departments of Hacettepe University or IMGE Child Mental Health Center and 154 children without any psychiatric diagnosis, who were receiving education from Nebahat Keskin Elementary School. Among 154 non-diagnosed subjects the ones who match best with the 77 ADHD group participants were chosen, considering ages of the children, income of the family, and education of the mother. Results and Discussion: (1) Psychometric Characteristics of the TBFI and CARSS were examined. The internal consistency coefficients of the TBFI varied from .51 (for Agreeableness) to .75 (for Neuroticism) and all subscales of CARSS had moderate to high degree of internal consistencies ranging from .65 (Conduct Disorder) to .92. (e.g., Attention Deficit). Additionally, concurrent validity of TBFI and criterion validity of CARSS were studied. Results revealed that TBFI had sufficient internal consistency and validity, and also revealed that CARSS was a highly reliable and valid measure, successfully differentiating the diagnosed group from the non-diagnosed group on each subscale. (2) Group differences on maternal characteristics were examined. Compared to non-diagnosed children, children with ADHD had mothers with higher Depression symptoms, higher Negative Affect, higher Neuroticism, lower Positive Affect. (3) Regression analyses, which were conducted separately for each group and the whole group, revealed that different maternal characteristics were associated with symptoms of diagnosed and non-diagnosed children. In general while symptom levels of children, who have ADHD diagnosis, was associated with higher maternal Negative and lower Positive Affect and higher Depression and Anxiety symptoms, and lower Extraversion scores / symptom level of Comparison children was associated more with Conscientiousness. These differences were explained by means of the fit between maternal characteristics and vulnerability, lower tolerance, lower adaptation, and compensation skills of children with ADHD (when compared to Comparison group). Results addressed the importance of maternal factors regarding its association with presence, and the severity of ADHD and comorbid symptoms of children.

Conduct Disorder (CD) is a repetitive and persistent pattern of behaviour in which the basic rights of others or major age-appropriate societal norms or rules are violated. It is one of the most common problems in South African schools, particularly in those that are poverty-stricken. The child who participated in the study lived in the shelter that was for homeless and disadvantaged children. He attended at Amasango School where the majority of children in the shelter attended. There were many conduct-disordered children in the shelter and the school, particularly in the school. They disrupted classes making in difficult for teachers to carry out their education activities. The aim of this study was to draw on the standard procedures of the CBT in order to design interventions that would be effective in reducing aggressive behaviour in an adolescent who had CD Adolescent-Type and who lived at the shelter. This case study evaluated the effectiveness of a multi-modal CBT programme in a 16 year-old Black male who had been displaying aggressive behaviour for about a year. The treatment consisted of 23 sessions and included teacher counseling, contingency management, self-control and self-instructional training. The treatment was evaluated qualitatively by means of interviews with the child and teacher and quantitatively by means of repeated applications of behaviour checklists completed by the teacher. The results showed a decrease in the client's aggressive behaviour and an increase in prosocial behaviour. The client ultimately ceased from all aggressive behaviour towards his peers and this outcome was sustained during his last two months in therapy.

As análises exploratórias revelaram que a RCS aumentada está associada a diversos tipos de comportamento de oposição e ofensivo relacionados ao comportamento agressivo [Pillai’s Trace=0,487; F(3,29)=9,189; p<0,001; Xp 2=0,487] e que apenas o primeiro estímulo aversivo foi responsável pela diferença entre adolescentes com níveis maiores e menores de comportamento opositor [F(9,197)=2,548; p=0,008]. Não se observou diferença significativa entre esses grupos e o número de estímulo até habituação. Este foi o primeiro estudo a investigar os aspectos psicofisiológicos de comportamento de oposição por meio da RCS em adolescentes. Os resultados confirmam a hipótese de que a resposta autonômica simpática pode variar de acordo com as dimensões de comportamento de oposição. Apesar das limitações do estudo, os achados auxiliam na validação das distintas dimensões do comportamento de oposição. / Oppositional behaviors during childhood are common, and are associated with symptoms of internalizing and externalizing. Oppositionality can negatively affect adolescence and adult life. Recent studies have shown that oppositionality encompasses three distinct dimensions with different predictive values of comorbidity: irritable, headstrong, and hurtful. Other studies suggest that both increased and reduced sympathetic skin response (SSR) are linked to antisocial and/or aggressive behavior. This response is called arousal. Our hypothesis is that the oppositionality dimensions are associated with increased levels of arousal. We aimed to examine the relationship between oppositional behavior dimensions and arousal levels in an adolescent sample. In addition, we studied the correlation between specific aggressive behavior, such as verbal, physical or social aggression and arousal levels. We also identified the link between the trajectory and number of aversive stimuli necessary for habituation to different oppositional dimensions. This is a cross-sectional study encompassing teenage students from public schools in the Hospital de Clínicas de Porto Alegre (HCPA) coverage area. Oppositionality and its dimensions were assessed with the Youth Self Report scale and aggressive behavior was evaluated with the Brazilian modified version of Olweus Bully/Victim Questionnaire. Arousability was assessed through SSR at the neurology department at HCPA. To assess SSR, we delivered 10 aversive stimuli to adolescents and measured the amplitude of each SSR generated. The association between oppositionality (dependent variable) and arousal (independent variable) was analyzed using general linear models and the exploratory analyses were studied with linear correlations and repeated covariance analyses. This study was approved by HCPA’s ethical committee. A total of 38 students with an average age of 13.84 (SD= 1.46) years were included in the study. Increased SSR was linked with oppositional behavior [Pillai’s Trace=0.234; F(2.33)=5.037; p=0.012; Xp 2 = 0.234] and girls showed higher levels of oppositional behavior [Pillai’s Trace=0.219; F(2.33)=4.637; p=0.017; Xp 2= .219]. However, this correlation is specific to headstrong/ hurtful dimensions [F(1.34)=7.802; p=0.009; Xp 2 0.187]. There was no link between arousal and age. The exploratory analyses showed that increased SSR is associated with several types of headstrong/hurtful behaviors related to bullying [Pillai’s Trace=0.487; F(3.29)=9.189; p<0.001; Xp 2=0.487] and only the first aversive stimulus was responsible for the difference between adolescents with high and low oppositional behavior scores [F(9.197)=2.548; p=0.008]. There were no differences between these groups in terms of the number of stimulinecessary for habituation. This is the first study to examine the psychophysiological aspects of oppositional behaviors in an adolescent community sample using SSR. The results confirm our hypothesis that sympathetic autonomic response can vary based on types of oppositional behavior. Despite our limitations, the results help validate the different dimensions of oppositionality and indicate that oppositional behaviors are modulated by both environmental and biological factors.

Increasing numbers of children being referred for mental health services are exhibiting problematic behaviors that can be subsumed under the category of Disruptive Behavior Disorders. This study with its foundations in a post-positivist approach was designed to explore treatment effectiveness of cognitive behavioral intervention applied to adolescents at Oak Grove Institute, a residential treatment facility. This study hypothesized that Wexler's PRISM Model, with its integration of affect, would be instrumental in modifying disruptive behavior as measured at Oak Grove Institute. Although the small sample size precluded statistically significant findings, there were interesting results with respect to two dependant variables. Findings approached significance on measures of impulsivity and verbal aggression. That is, impulsivity and verbal aggression scores were lowered.
