OBJECTIVE: To examine the past-year prevalence and frequency of condom use and to identify correlates of condom use among young, unattached heterosexual Ontarians. METHODS: Descriptive statistics and multiple logistic regression were used to analyze the 1996/97 Ontario Health Survey (OHS), a cross-sectional, random digit-dialling (RDD) survey of 36,892 Ontario residents of households with a telephone line. RESULTS: Between 1996 and 1997, 61.3% (95% CI=58.5%-64.1%) of the study sample (aged 15-44, n=1,949) reported consistent (always) condom use and 11.8% (95% CI=10.2%-13.5%) reported never using condoms. Significant correlates included, for both sexes, health planning region, age, ethnic origin, and type of smoker; for females only, socio-economic status, age at first sexual intercourse, and past-month oral contraceptive use ; and for males only, number of past-year sexual partners, HIV testing history, and past-year frequency of religious attendance. CONCLUSIONS: Findings constitute a cross-sectional component for examining the long-term trend of condom use in Ontario.

The distinction of positive and negative symptoms in schizophrenia was examined in relation to demographic, clinical and neuropsychological measures.

The purpose of this study was to examine differences in anxiety levels between the sexes and between sex role identification groups (as defined by scores on a test of masculinity-femininity). Possible explanations for these differences were explored using a questionnaire made up of an openness versus closedness scale, a liberalism versus conservatism scale, and a cross-sex versus same-sex parent identification scale. A sample of 108 females and 71 males was administered Gough's Femininity Scale, Cattell's IPAT Anxiety Scale Questionnaire, Taylor's Manifest Anxiety Scale, and a questionnaire devised for this particular study. The sexes did not differ significantly in anxiety level but it was found that feminine persons of both sexes had higher anxiety levels on both of the anxiety scales employed. Females were more open than males on the openness versus closedness scale and feminine persons of both sexes were more open than masculine persons. This study suggests the possibility that higher anxiety levels in females and feminine persons may be due to greater openness.

The State of Texas accepted the Effective School Research model and its correlates as a way of determining whether the state’s schools are effective. This included all juvenile justice alternative educational facilities. The purpose of the study was to assess the relevance of the Effective School Correlates to alternative educational settings for students in a correctional system as identified by the teachers and administrators in selected charter schools in Harris County, Texas. Secondly, the study was to suggest modification to the Effective School Correlates to make them relevant to an alternative educational setting for students in the correctional system in selected charter schools in Harris County, Texas. The literature revealed a potential lack of fit between the Effective School Correlates as the “Key Characteristic of Effective Schools” and their relevance to the context of alternative schools for students in the correctional systems. This study led to the postulation that the Effective School Correlates as written may need altering to meet the needs of the specialized correctional school setting. However, it is not clear what shape or direction this alteration would take. Findings of this study indicated that problems existed with the application of the Correlates as they related to the selected Charter Schools in Harris County, Texas. The population size limited the study and caution should be taken not to over-generalize the data.

Background Information: There is substantial evidence demonstrating the significant benefits of regular physical activity (PA) and the burden of morbidity and mortality associated with inactivity. In Australia however, approximately 40% of the adult population is not meeting recommended levels of PA, the rates of inactivity may be increasing, and improving population levels of PA has been identified as a public health priority. Research is needed therefore, to develop a better understanding of the variables that limit and facilitate PA levels within the population, so as to guide the development of population-based PA promotion. Although a range of psychological, social and environmental variables have been associated with PA, few studies have integrated correlates across these domains and compared their relative contribution. The current evidence base is also limited by too few population-based studies, insufficient assessment of the measurement properties of correlate scales, minimal information on PA item non-response, and a lack of specificity among PA domains. Aims: This research program aimed to develop measures and examine the relative contributions of self-reported psychological, social, and environmental variables to explain variation in leisure-time PA (LTPA) among adults in the general population. Methods: This research program comprised three studies that utilised a crosssectional design and a mail survey methodology with a population-based random sample drawn from Brisbane, Australia (N=5000). Study one involved development and assessment of the measurement properties of a battery of scales to measure correlates of LTPA, using principal components and internal reliability analyses. Study two assessed the magnitude of and sociodemographic variables associated with LTPA item non-response on the mail survey, using logistic regression. Study three examined the independent contributions of self-reported psychological, social, and environmental variables to variation in walking, moderate- and vigorousintensity LTPA, using logistic regression adjusted for sociodemographic covariates. Results: Study one produced a battery of 28 scales to assess self-reported psychological, social and environmental correlates of LTPA. The scales used a total of 123 items to measure activity history (habit, mastery, exposure), health (physical, psychological), activity-related cognitions (self schemata, activity schemata, demand, need, knowledge), self-efficacy, anticipated benefits (psychological, health, challenge, improved appearance, social, weight management), perceived barriers (expense/low access, poor skill, poor personal functioning, time organization, disinterest, family obligations), social support (encouragement, discouragement) and neighborhood environment (available facilities, physical characteristics, aesthetic features, traffic). Of the 28 scales that were factorially derived, 25 had acceptable or marginal levels of internal consistency with Cronbach's alpha values ranging from 0.65 to 0.89. Study two indicated that 28% of the mail survey respondents had incomplete LTPA data with 8% of respondents missing the walking item, and 18% and 23% missing the vigorous-intensity and moderate-intensity LTPA items respectively. Respondents who missed all three LTPA items were more likely than those with complete LTPA data to be female, less educated, from low-income households, in poor health, and a current smoker. Respondents who missed the walking item were significantly more likely to be a current smoker, and to have limited education and low household income. Incomplete moderate-intensity LTPA data was associated with single parenthood and vocational education. Those who missed the vigorousintensity LTPA item were more likely to be 35-54 years old, in fair or poor health, and obese. Respondents with incomplete LTPA data were also more likely to miss sociodemographic items assessing education, household composition, and household income. In study three, the sociodemographic and correlate variables collectively accounted for 43% of the variation in total LTPA, 45% of vigorous-intensity LTPA, 26%of walking, and 22% of moderate-intensity LTPA (Nagelkerke R square). The individual correlates accounted for 0.0 - 4.0% of unique variation across the different domains of LTPA. Habit, self-efficacy, and social encouragement tended to contribute more unique variation for each LTPA domain. Physical health, discouragement, competition, and time management barriers contributed more unique variation to vigorous-intensity LTPA. Anticipated benefits of social interactions and weight management contributed more unique variation to moderate-intensity LTPA. Neighbourhood aesthetics contributed more unique variation to walking variation. Conclusions. This research program demonstrates the importance of integrating psychological, social, and environmental variables to explain PA, and that the relative importance of these correlates is likely to differ among PA domains. More research is needed to enhance the conceptualisation and measurement of correlate variables, in particular PA opportunities across the lifecourse, the anticipated benefit of a balanced lifestyle, the barriers of an unpredictable lifestyle and family obligations, social discouragement, and environmental variables. Population-based mail surveys of LTPA may under-represent population subgroups that are insufficiently active for health, and proactive strategies are needed to maximise their full participation in research and obtain complete survey data, in particular among individuals of low socioeconomic position and for the assessment of moderateintensity LTPA. Generic promotion to increase overall levels of LTPA in the population could focus on promoting self-efficacy for PA and habitual LTPA, as well as enhancing social encouragement. Tailored promotion for vigorous-intensity LTPA could reduce barriers associated with physical health, discouragement, competitiveness, and time management. Tailored promotion for moderate-intensity LTPA and walking should focus on supportive local neighbourhoods and promote the benefits of weight management and social interactions. In time, the successful implementation of such policy and promotion may arrest the decline of PA levels in the population, reduce preventable morbidity and mortality and economic burden associated with inactivity, and facilitate improved health for all Australians.

The purpose of this study was to examine the relationship between perfectionism and social anxiety in general as well as social phobia, specifically. Subjects completed the Personal Standards Scale, the Fear of Negative Evaluation scale, and the Social Phobia and Agoraphobia Inventory. Results indicated that neurotic perfectionism is positively associated with both general social anxiety and social phobia. Moreover, the neurotic elements of perfectionism -- "concern over making mistakes" and "doubts about actions" -- appeared to be better predictors of social anxiety than high performance standards alone. Differences between social phobia and social anxiety secondary to agoraphobia as related to perfectionism were addressed, and directions for future research are discussed.

Burnout is a condition that results from chronic work-related stress, and it is associated with impairments in cognitive and emotion-related functions, such as impaired executive functions and emotion regulation. This thesis aimed to conduct a systematic review of the neural correlates of burnout. The thesis investigates the following research question: do the neural correlates of burnout involve the same brain regions and/or functions as those implicated in the cognitive functions affected by burnout? The systematic literature search resulted in seven studies which studied either the functional, structural, or electrophysiological correlates of burnout. The results showed that burnout involves functional and structural alterations in regions involved in various higher-order cognitive functions. Structural findings indicate alterations in brain regions involved with emotion processing, memory and attention (i.e., medial prefrontal cortex, caudate, amygdala). Electrophysiological findings indicate differences in alpha power in burnout individuals compared to controls, suggesting that alpha power is reduced when burnout's specific symptoms (i.e., exhaustion) increase. Evident are also findings on functional differences in working memory (dorsolateral prefrontal cortex) and reduced functional connectivity between emotion processing areas (the amygdala and anterior cingulate cortex) and areas such as the motor cortex. The presented findings answer the research question. It can be concluded that the brain regions implicated in the cognitive functions affected by burnout resemble many of the regions affected in the neural correlates of burnout. Future studies should take into account the methodological issues of the existing studies.

Temporal context memory is a type of episodic memory that refers to memory for the timing of events. Temporal context includes environmental cues that provide information about the time point at which an event happened. The purpose of the present studies is to investigate the brain mechanisms underlying temporal context processing by using both fMRI and ERP techniques. The fMRI study investigated whether hippocampal representations in CA1 and DG/CA3 subfields were sensitive to the flow of physical time, and if so, whether the number of events that occur during a time period influences the temporal representation of a target event. Results showed that both CA1 and DG/CA3 were sensitive to the flow of physical time, which was indicated by higher representational similarity between two pictures that occurred closer in time than those that occurred more distant in time. However, the variety of preceding events did not influence temporal representation, which was demonstrated by the lack of a significant representational similarity difference between two pictures that were interleaved with variable events as opposed to similar events. The ERP study compared the ERP correlates of temporal to spatial context. Results showed that temporal and spatial contexts had overlapping ERP effects except that the ERP effects of temporal context were more frontally distributed than spatial context. Both the fMRI and ERP studies indicate that temporal context is associated with similar neural correlates to other types of context in episodic memory. / Ph. D.

Immunological correlates of anger conditions were investigated. Participants were 33 females and 36 males, ranging from 25 to 55 years old. Percentages of total T-lymphocytes, suppressor-T, helper-T, and ratio of helper-T to suppressor-T cells were measured. Differences were found between males and females for Anger Control and Anger Expression. For females, total T-cell percentages correlated with State Anger, Angry Temperament, Anger Out, and the combination of State Anger/Angry Reaction. Suppressor-T cell percentages correlated with State Anger, Trait Anger, Angry Temperament, Anger Out, Anger Expression, and the combination of Angry Temperament/Anger In. Helper-T cells correlated with State Anger, Angry Temperament, Angry Reaction, Anger Out, and Anger Control. Mindbody appears to function in a unified fashion.
