Information processing biases concurrently and prospectively predict depressive symptoms in adolescents: Evidence from a self-referent encoding task

Negative information processing biases have been hypothesised to serve as precursors for the development of depression. The current study examined negative self-referent information processing and depressive symptoms in a community sample of adolescents (N = 291, M_age at baseline = 12.34 ± 0.61, 53% female, 47.4% African-American, 49.5% Caucasian and 3.1% Biracial). Participants completed a computerised self-referent encoding task (SRET) and a measure of depressive symptoms at baseline and completed an additional measure of depressive symptoms nine months later. Several negative information processing biases on the SRET were associated with concurrent depressive symptoms and predicted increases in depressive symptoms at follow-up. Findings partially support the hypothesis that negative information processing biases are associated with depressive symptoms in a nonclinical sample of adolescents, and provide preliminary evidence that these biases prospectively predict increases in depressive symptoms.     

The influence of suggestions on children's reports of a unique experience versus an instance of a repeated experience

In Experiment 1 we compared the influence of misleading suggestions on 4‐, 6‐, and 8‐year‐olds' reports of details of an instance of a repeated experience versus a unique experience. For children who experienced the event repeatedly, some components remained constant across instances (fixed) whereas others varied (variable). Relative to children who had experienced the event only once, those who had experienced it repeatedly were less affected by suggestions regarding fixed details and more affected by suggestions regarding variable details. In Experiment 2 a misinformation effect was observed in responses to questions about variable details but not in responses to questions about fixed details.

Psychological state and psychological strain in relation to infertility

The purpose of the study was to explore the relationship between psychological state and perceived strain in relation to fertility problems. Couples presenting at an infertility clinic completed, on two occasions seven months apart, a series of standardized measures to assess psychopathology. In addition, they completed a weekly diary rating their mood state or distress/strain over a period of 22 weeks, during which investigations and treatment were taking place. Little evidence of psychopathology was found in the sample; the weekly diaries also suggested a general lack of distress/strain, even in response to medical investigations and diagnosis. The results are discussed in the light of wide individual variations in ratings obtained from the diaries. Participants with high distress/strain scores tended to have significantly higher initial scores on the psychometric measures administered. Participants with high distress/strain scores were also more likely to show a further significant increase in distress/strain scores in relation to diagnostic information. It is argued that a task for future research is to determine the characteristics of those couples who are likely to experience difficulty in coping with the strain of infertility investigations so that counselling resources and support services can be most effectively targeted. © 1998 John Wiley & Sons, Ltd.     

Analyzing Additional Variables in the Theory of Reasoned Action

This study examined the convergent, discriminant, and predictive validity of several variables proposed to augment the theory of reasoned action (TRA), using both principal components analysis (PCA)/multiple regression and confirmatory factor analysis (CFA)/structural equation modeling (SEM) among a sample of the UK population regarding their intention to have a child. PCA revealed good convergent and discriminant validity for attitude vs. anticipated regret, subjective norm vs. moral norm vs. social relations, but not for intention vs. desire or perceived behavioral control. Multiple regression analyses showed that the additional variables predicted a significant increment in the variance in intention. CFA, however, showed moderate convergent validity and poor discriminant validity and the structural model comprised the 2 predictors from the TRA only.     

Predicting Affective Responses to Unexpected Outcomes

In decisions under uncertainty, decision makers confront two uncertainties: the uncertain linkage between actions and outcomes and the uncertain linkage between these outcomes and his or her affective responses to them. The two studies reported here examine affective responses to expected and unexpected outcomes in various settings. In Study 1, a scenario-based laboratory experiment (N = 149), we examined subjects' predicted responses to a range of outcomes, as a function of how surprising the outcome was. Study 2, a field study (N = 127), involved the expectations of bowlers about their scores in an upcoming game and about their responses to various outcomes at, above, and below expectations. We also measured actual affective reactions after the bowlers had completed their games. Findings suggest that subjects both expect and experience a loss-averse, expectation-based value function broadly of the Prospect Theory type. They also anticipate, and experience, an amplifying effect of outcome surprise, though they underestimate its size. We argue that such underestimation, together with overtight prediction ranges, may expose subjects to much larger affective variation with outcome variability than they anticipate.
