Hierarchical Model of Generalized and Specific Vulnerabilities in Anxiety

This study evaluated a theoretical hierarchical relationship among the general anxiety vulnerability variable of neuroticism, the specific vulnerability variables of anxiety sensitivity and intolerance of uncertainty, and variables reflecting specific anxiety foci including panic symptoms, health anxiety, obsessive-compulsive symptoms and generalized anxiety/worry. Questionnaires assessing these variables were administered to a non-clinical sample of 91 first-year psychology students (64.8% women). Path analysis results were highly consistent with the hypothesized hierarchical model. Neuroticism was found to have a significant direct effect on both anxiety sensitivity and intolerance of uncertainty. Both neuroticism and anxiety sensitivity had direct significant effects on panic symptoms, neuroticism and intolerance of uncertainty both made significant direct contributions to the prediction of worry, and neuroticism made a significant direct contribution to the prediction of obsessive-compulsive symptoms. Contrary to the hypothesized model, anxiety sensitivity but not neuroticism uniquely predicted health anxiety. The results of this study provide initial empirical evidence for a hierarchical relationship among general and specific vulnerabilities, and specific anxiety manifestations.     

Peer Victimization in Middle School

ABSTRACT

African American (n = 350) and Latino (n = 435) 6th grade students from eight middle schools completed self-report measures of peer victimization and psychological adjustment (i.e., self-esteem, anxiety, loneliness, depression, and physical symptoms). Peer nomination procedures were used to determine which students had reputations as victims and which students were accepted, rejected, and perceived as most «cool.» In addition, homeroom teachers rated participating students on social behavior and academic engagement and students' grades were collected from school records. We created four victim groups based on self-and peer perceptions. «True» victims (agreement between self and peer) experienced the worst outcomes on all of the adjustment variables examined. However, different adjustment difficulties were reported for victim groups where there was disagreement between self-and peer views. Self-perceived victimization was predictive of psychological maladjustment, whereas the reputational measure was more related to peer rejection and negative teacher ratings. The implications of the findings for both accurate identification of victims of harassment and targeted intervention strategies were discussed.     

Predicting physical activity in adolescents: The role of compensatory health beliefs within the Health Action Process Approach

Objective: Compensatory health beliefs (CHBs), defined as beliefs that healthy behaviours can compensate for unhealthy behaviours, may be one possible factor hindering people in adopting a healthier lifestyle. This study examined the contribution of CHBs to the prediction of adolescents’ physical activity within the theoretical framework of the Health Action Process Approach (HAPA).

Design: The study followed a prospective survey design with assessments at baseline (T1) and two weeks later (T2).

Method: Questionnaire data on physical activity, HAPA variables and CHBs were obtained twice from 430 adolescents of four different Swiss schools. Multilevel modelling was applied.

Results: CHBs added significantly to the prediction of intentions and change in intentions, in that higher CHBs were associated with lower intentions to be physically active at T2 and a reduction in intentions from T1 to T2. No effect of CHBs emerged for the prediction of self-reported levels of physical activity at T2 and change in physical activity from T1 to T2.

Conclusion: Findings emphasise the relevance of examining CHBs in the context of an established health behaviour change model and suggest that CHBs are of particular importance in the process of intention formation.     

Does change in positive affect mediate and/or moderate the impact of symptom distress on psychological adjustment after cancer diagnosis? A prospective analysis

This study tested the predictive value of the Transtheoretical Model (TTM) for the preparation to action stage transition by conducting a detailed examination of changes in TTM components in the days leading up to, and following, a planned quit attempt. Participants were 193 callers to a Quitline telephone service. Only limited support for the TTM was found. Consistent with the TTM, measures of self-efficacy were related to making an attempt and to achieving 7 + days of abstinence. Contrary to the TTM, the behavioral change processes were unrelated to making quit attempts and to short-term abstinence, with the exception of self-liberation, which is conceptually related to self-efficacy. New non-TTM measures assessing commitment to quitting were predictive of outcomes. The results provide strong support for the preparation to action transition being discontinuous, and thus consistent with a stage model. However, they bring into question many of the other postulates of the TTM. Further critical testing and evaluation of the TTM is required.     

Evidence for Discontinuity Patterns Across the Stages of Change: A Role for Attitudinal Ambivalence

Cross-sectional analyses of the transtheoretical ("stages of change") model (TTM) can provide valuable information concerning the variables that are likely to shift individuals from one stage to the next. The present study was designed to investigate the roles of theory of planned behaviour (TPB) variables and attitudinal ambivalence across the stages of change. Two samples derived from the general population completed measures of stage, TPB and attitudinal ambivalence with respect to consuming a low-fat diet (n = 148) and eating five portions of fruit and vegetables per day (n = 151). Consistent with previous research, the present study found linear increases in TPB variables across the stages of change. However, as predicted, attitudinal ambivalence showed discontinuity patterns, displaying a quadratic relationship with the stages of change, such that least ambivalence was experienced in the precontemplation and maintenance stages. Discussion of the findings focuses on implications for the development of theory-driven interventions.     

Women's expectations and experience of birth

Empirical research has identified two distinct item clusters used to measure perceived behavioral control (PBC) labeled self-efficacy and controllability. Self-efficacy has been reported as the superior predictor of intention in all research efforts with these PBC factors. However, we argue that the conception of these item clusters originates from backward theorizing and hypothesize that controllability items are better indicators of the originally conceived PBC construct, while self-efficacy taps the measurement domains of both PBC and intention. Therefore, the purpose of this study was to investigate factor distinction with PBC and intention items across disparate samples of 302 undergraduate students and 267 cancer survivors in the exercise domain. Results found the only model with acceptable fit across populations was that of controllability and intention ( h 2 (8) = 6.91, p = 0.55; RMSEA = 0.00; CFI = 1.00 for undergraduates and h 2 (8) = 26.51, p <0.01; RMSEA = 0.09; CFI = 0.97 for cancer survivors) supporting our hypothesis that the controllability concept, but not the self-efficacy factor, has a clean measurement distinction from intention. Further, self-efficacy items showed factor complexity between PBC and intention across both samples, suggesting that self-efficacy may have been reported as superior to controllability in predicting intention due to measurement redundancy rather than meaningful causal influence.     

Interdependence of Stress Processes Among African American Family Members: Influence of HIV Serostatus and a New Infant

This study makes a theoretical contribution to stress process research by using a systemic approach to contextualize individual outcomes within the framework of other family members' experience. Utilizing a mixed model approach, indicators of the stress process of urban low-income HIV + African American recent mothers were found to affect the psychological distress and perceived adequacy of coping of multiple other family members. These relationships were found to be strongest proximal to birth and to be exacerbated by HIV infection. Social support to the mother was found to have differential effects depending on whether it was from the immediate family or outside sources. HIV infection of the recent mother was found to affect family members both through relationships of the mother's stress process and through their own coping responses.     

Psychological Risk Factors of Sudden Cardiac Arrest

This study tested the hypotheses that Vital Exhaustion (VE) increases the risk of sudden cardiac arrest (SCA) and that non-expression of emotions modifies the risk of VE. Data came from 99 victims of SCA and 103 healthy controls matched for gender and age. Victims of SCA were more often assessed as exhausted and as being closed by their family members than controls, the estimated relative risks being 2.81 (95% CI 1.1-7.3) and 2.28 (95% CI 1.1-4.6), respectively. No significant interaction between exhaustion and being closed on the risk of SCA was observed. These findings indicate that a state of exhaustion and being closed belong to the risk indicators of SCA.     

Divergent viewpoints about lineups: What policy for the identification of criminals?

IntroductionA fair lineup is needed to maximize the likelihood of correct identification of the criminal and minimize the likelihood of mistaken identification. Fairness depends on distractor plausibility and the lineup method (i.e., simultaneous or sequential).ObjectiveThis paper aims to evaluate the advantages and the limits of distractor plausibility and the presentation of the lineup members, and thus show the best method to ensure correct identification.MethodOur conclusions are based on the major experiments published in the field and on recent debates in the scientific community.Results and conclusionIn addition to distractor plausibility, our conclusions, which are based on previous work by Malpass (2006), suggest that sequential and simultaneous lineups are complementary rather than opposed. The paper argues that two tools specifically designed for and adapted to particular situations are better than one.     

The psychogenesis of the ego: notes on Freud's 'case of homosexuality in a woman'

This paper examines Freud's (1920) case study 'The psychogenesis of homosexuality in a woman' in the light of the second topography that was being elaborated in his theoretical writing at that time. The analysis of the ego and its defence mechanisms, which was to become such an important part of clinical technique in Anglo-American psychoanalysis, psychoanalytic psychotherapy and psychodynamic counselling, is not set out explicitly in any of Freud's case studies. However, in this last case study presented by Freud, it is possible to see how an attention to family dynamics, Oedipal structures and patterns of identification set the stage for the new notion of the ego to emerge. This 'turning point' in theory and clinical technique is also, in this case, intimately related to theories of sexuality, and Freud's own assumptions about homosexuality and heterosexuality are considered here in relation to his account of the ego.
