Prospective cognitions in anxiety and depression: Replication and methodological extension

The present study presents a replication and methodological extension of MacLeod, Tata, Kentish, and Jacobsen (1997) with a nonclinical sample, using future-directed imagery to assess prospective cognitions. Results showed that only anxiety (but not depression) was related to enhanced imagery for future negative events. Both anxiety and depression showed significant zero-order correlations with reduced imagery for future positive events. However, when the overlap between anxiety and depression was controlled for, only depression (but not anxiety) showed a unique association with reduced imagery for positive events. Implications of these findings for cognitive models of anxiety and depression are discussed

Capacity and Opportunity: Predicting Engagement for Middle School Students With Behavioral Disorders

This study examined the capacity and opportunity scores of 36 middle school students with emotional and behavioral disorders (EBD) on the student version of the American Institutes for Research (AIR) Self-Determination Scale across three school engagement factors: grade point averages (GPA), school absences, and frequency of school disciplinary encounters. Poor grades, school absences, and frequency of disciplinary actions pose academic problems for middle school students with EBD. Three multiple regression models determined the predictive relationships between self-determination Capacity and Opportunity subscale scores and GPA, Absences, and Discipline. Higher capacity and opportunity scores predicted greater student GPA, fewer student absences, and fewer disciplinary encounters for students at school. Results of this study demonstrate the need for increased opportunities at school and home for students with EBD to learn and practice self-determination skills.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Exploring the psychosocial and behavioural determinants of household water conservation and intention

Securing urban freshwater supplies is a major challenge for policy makers globally. This study investigated the determinants of household water conservation to identify the relative contribution of psychosocial and behavioural determinants. Using a survey of 1196 households across the UK, we found that attitudes, norms and habits play an important role in determining intention to conserve water, and that habits were the single most important predictor of water conservation intentions and self-reported water bills. Changing ingrained water conservation habits is therefore an important component of managing urban water demand

Validating an adapted questionnaire to measure belongingness of medical students in clinical settings

Introduction: Belongingness is a key factor that influences learner development and wellbeing, but no previous research has been performed to evaluate perceived belongingness in medical students whilst on their placements. Method: The Belongingness Scale-Clinical Placement Experience (BES-CPE) for nursing students was adapted for use with medical students. Following a face validity assessment, 490 undergraduate medical students in years three to five at a UK university were invited to participate and 302 completed the adapted questionnaire. The factor structure was explored using Exploratory Factor Analysis (EFA) with Principal Component Analysis (PCA) and internal consistency was assessed using Cronbach’s alpha. Results: A three-component structure was identified (Esteem, Connectedness, and Efficacy), which was aligned to the original theoretical model underpinning the scale, and the instrument had high internal consistency. Four items were discarded and the final adapted version had a total of 30. Conclusions: The adapted BES-CPE instrument for medical students in our sample of UK undergraduate medical students had an appropriate factor structure and high internal consistency. This context-specific instrument can be used for future research as a valid instrument to measure the role of belongingness in medical education and to support developing belongingness in medical students during clinical placements

Cooccurrence of prey species alters the impact of predators on prey performance through multiple mechanisms

When prey are differentially affected by intra and interspecific competition, the cooccurrence of multiple prey species alters the per capita availability of food for a particular prey species which could alter how prey respond to the threat of predation, and hence the overall�effect of predators. We conducted an experiment to examine the extent to which the nonconsumptive and overall effect of predatory water bugs on snail and tadpole traits (performance and morphology) depended on whether tadpoles and snails cooccurred. Tadpoles and snails differed in their relative susceptibility to intraspecific and interspecific competition, and predators affected both prey species via consumptive and nonconsumptive mechanisms. Furthermore, the overall effect of predators often depended on whether another prey species was present. The reasoning for why the overall effect of predators depended on whether prey species cooccurred, however, differed for each of the response variables. Predators affected snail body growth via nonconsumptive mechanisms, but the change in the overall effect of predators on snail body growth was attributable to how snails responded to competition in the absence of predators, rather than a change in how snails responded to the threat of predation. Predators did not affect tadpole body growth via nonconsumptive mechanisms, but the greater vulnerability of competitively superior prey (snails) to predators increased the strength of consumptive mechanisms (and hence the overall effect) through which predators affected tadpole growth. Predators affected tadpole morphology via nonconsumptive mechanisms, but the greater propensity for predators to kill competitively superior prey (snails) enhanced the ability of tadpoles to alter their morphology in response to the threat of predation by creating an environment where tadpoles had a higher per capita supply of food available to invest in the development of morphological defenses. Our work indicates that the mechanisms through which predators affect prey depends on the other members of the community

Pornography, preference for porn‐like sex, masturbation, and men's sexual and relationship satisfaction

Pornography use, preference for “porn‐like” sex, masturbation, and sexual and relationship satisfaction were assessed among two samples of men (NStudy 1 = 326, NStudy 2 = 335). Frequent pornography use was associated with sexual dissatisfaction, greater preference for porn‐like sex, and more frequent masturbation in both studies. Pornography use was associated with relationship dissatisfaction in Study 2 only. The data did not support the notion that pornography negatively impacts sexual or relationship satisfaction via preference for porn‐like sex. In fact, it may bolster sexual satisfaction by promoting sexual variety. The data were consistent with a model in which pornography negatively, indirectly affects sexual and relationship satisfaction via masturbation frequency. Pornography use may have multiple opposing influences on sexual satisfaction

‘I am worthless and kind’: the specificity of positive and negative self-evaluation in adolescent depression

Objectives: Adolescence represents a critical phase when the concept of self is developed and consolidated. Depressed adolescents globally endorse more negative and fewer positive self-descriptive words compared with non-depressed adolescents. Yet the methods used have not allowed for more detailed exploration of the specific content of these self-endorsements. Methods: Adolescents, aged 12-18 years, were recruited from the community (n = 204) and from a child and adolescent mental health service in the UK (n = 87). Participants completed measures of depression and a self-description questionnaire which included 12 positive and 12 negative self-descriptive adjectives. Results: As expected, we replicated previous findings that depressive symptoms are associated with global positive and negative self-endorsements. The difference between mean scores was examined for each adjective. Depressed adolescents endorsed all negative adjectives more highly relative to community adolescents; ratings of ‘worthless’ and ‘useless’ had the biggest difference between community and depressed adolescents. Surprisingly, a group of positive prosocial self-descriptors were endorsed equally by depressed and community adolescents and were not associated with severity of depressive symptoms. Conclusions: Although depressed adolescents endorsed more negative descriptions of themselves than community adolescents, positive self-endorsements related to their relationships with other people were not impaired

Perfectionism and training distress in junior athletes: A longitudinal investigation

Perfectionistic athletes may train harder and for longer than non-perfectionistic athletes, leaving them susceptible to elevated levels of training distress. So far, however, no study has investigated the relationships between perfectionism and training distress, a key indicator of overtraining syndrome. Furthermore, no study has determined psychological predictors of overtraining syndrome. Using a two-wave design, the present study examined perfectionistic strivings, perfectionistic concerns, and training distress in 141 junior athletes (mean age 17.3 years, range 16-19 years) over 3 months of active training. Multiple regression analyses were employed to test cross-sectional and longitudinal relationships between perfectionism and training distress. In all analyses, perfectionism emerged as a significant predictor, but strivings and concerns showed differential relationships. When the cross-sectional relationships were regarded, perfectionistic concerns positively predicted training distress (p .05). The findings suggest that sports scientists who wish to identify athletes at risk of overtraining syndrome may monitor athletes’ perfectionistic concerns as a possible risk factor
