This thesis was designed to investigate differences in aggression between girls with and without attention-deficit/hyperactivity disorder (ADHD). Forty girls with ADHD and 43 girls without ADHD aged 9- to 12- years and their mothers and teachers participated. A multiassessment methodology was used to investigate these differences, employing mothers' reports, teachers' reports, and a laboratory aggression analogue task (a computer game involving simulated girls in other rooms). The results indicated that mothers and teachers saw girls with ADHD as having much higher levels of all types of aggression assessed, including overt, relational, proactive, and reactive aggression, than girls in the control group. On the lab task, girls with ADHD used a strategy that involved more threatening and bragging comments, and social exclusions of their co-players. Expected differences on some of the lab task measures did not emerge. Also, according to mothers, teachers, and the results from the lab task, girls with ADHD were significantly less prosocial than girls in the control group. Where significant group differences had been found, follow-up tests generally indicated that girls with ADHD and comorbid oppositional-defiant disorder (ODD) were more aggressive than girls in the control group, with girls with ADHD but not ODD falling in between. In sum, these results indicate substantial cause for concern for the concurrent and future psychosocial well-being of girls with ADHD. / Arts, Faculty of / Psychology, Department of / Graduate

This thesis aimed at examining, in the middle of an intense sociopolitical crisis in the Greek landscape, how young users of alternative media in Greece reflect on traditional media, how they view alternative media and how they use them in order to mobilize, engage politically and acquire types of oppositional knowledge. In-depth interviews on Greek millennials indicated a cognitive-driven relationship to mainstream media while a generic tendency towards alternative media was notived, however, accompanied by a critical stance. Political participation was present on both ffline and online version, with an apparent inclination to online types through e-petitions and expressive forms of action, such as content sharing and posts on social media. Oppositional types of knowledge were identified through the millennials' responses, though, with a presence of reservedness and critique. The shift towards alternative media depicted the emergence of a concrete digital familiarization of Greek millennials who seriously engage to sociopolitical issues and at the same time preserve their doubts as far as credibility or objectivity of news are concerned. Future research could be conducted focusing on the content analysis of alternative media news platforms. Therefore, micro-organizational aspects, such as agenda-setting and news production along with ethical lines that are followed, would enrich the picture of alternative media landscape in Greece and maybe provide the motivation to examine the aforementioned conditions in other media systems, as well.

This research study compared perceptions of family functioning among preadolescent children with behavior difficulties and their primary caregivers. Participants consisted of 29 caregiver-child dyads as well as each child's classroom teacher. Eligibility for the study was based on the child's placement within a self-contained Emotionally Handicapped (EH) or Severely Emotionally Disturbed (SED) classroom in one of three elementary schools within two west coast Florida counties. Data collection included teacher rating scales pertaining to the severity of each child's behavior and the presence of Callus Unemotional (CU) traits in addition to caregiver and child interviews tapping perceptions of family functioning. Results indicated that caregivers consistently viewed their families as more adaptive and cohesive than did children with a disruptive behavior disorder. These findings are consistent with previous research showing a similar pattern among older adolescents with a disruptive behavior disorder. No relationship was not found between the child's perception of family functioning and CU traits, although it was noted that there was considerable restriction of range on CU traits. Overall, the results of this study contributes to the existing literature by demonstrating that preadolescents, like their older counterparts, also view their families as less adaptive and cohesive than do their caregivers. Limitations and directions for future research are discussed.

Although there is a growing international consensus of adopting progressive abortion laws, we also see a backlash of reproductive health regulation across the globe, for example in Poland. In contrast to the existing literature on abortion in Poland, this thesis explores pro-choice advocates’ strategies in relation to their oppositional forces. To do so, pro-choice activities surrounding the near-total ban of abortion in 2020 and 2021 are studied through interpretative content analysis of pro-choice advocates’ websites, one Annual Report, and interviews with pro-choice advocates. Using previous research on how to capture resistance and well-grounded concept deriving from social movement theory, this study establishes how the strategies of pro- choice advocates are affected by their oppositional forces. The analysis showcases that the pro- choice advocates perceive Poland as a hub for far-right and conservative groups, and establishes that they are aware of the resistance they meet, including their maneuver possibilities and limitations in the political and institutional context. Pro-choice advocates need to expand their services and use alternative strategies to circumvent oppositional forces’ actions and power. Due to the due to the impact of oppositional forces, the resources of rest, good relationships within one’s group, and the networks of these groups, i.e., the emotional dynamics of their strategies, to be crucial. Correspondingly, due to the oppositional forces’ actions, smaller pro-choice groups are found to a greater extent using reactive tactics than proactive. The dynamics of power, including the institutional context, are in favor of pro-choice advocates’ oppositional forces, however, this thesis also acknowledges how innovative and problem-solving pro-choice advocates are, although being led down by their government and the society in which they work. As such, this study brings valuable insights to supplement the existing theoretical knowledge concerning feminist movements’ resistance and oppositional dynamics in a case of gender-inequitable change.

This study examined the treatment outcomes for Oppositional Defiant Disorder by provider license type and therapy modality. Administrative data from Cigna Insurance Company for 9,904 ODD cases were analyzed to determine the cost, number of sessions, dropout rates, and recidivism rates for treatment of ODD. Descriptive statistics indicate that the mean cost of treatment for ODD across all professions is $389.83. Analyses revealed significant differences in total cost by profession, as well as cost per session for different license types with counselors providing therapy for the lowest average total cost, followed by MFTs, MSWs, Psychologists and then MDs. Chi square analyses revealed that in the treatment of Oppositional Defiant Disorder, MFTs have the lowest drop-out rate, followed by MSWs, then Counselors and Psychologists together, with MDs having the highest proportion of client drop-out. Results on re-admission rates rank MFTs with the lowest proportion of clients returning to care, followed by MDs, Counselors, MSWs, with Psychologists having the highest re-admission rate. When comparing outcomes by therapy modality, results of ANOVA tests indicate that family therapy is most cost-effective followed by individual, then mixed therapy modalities. Family therapy also had significantly fewer sessions than the other modalities.

A majority of research investigating aggression and its development in children has relied upon the use of rating scales such as the Child Behavior Checklist (CBCL). These scales are typically developed using a conventional factor analytic approach for the selection and retention of scale items, but may not contain sufficient numbers of items to adequately assess the unidimensional construct or developmental trajectory of aggressive behavior in youths. The present study evaluates specific psychometric properties of CBCL Aggressive and Delinquency Problems clinical syndrome scale items to determine the degree to which they reflect the breadth and established developmental trajectory of aggressive behavior in youth.
