Social isolation, psychological health, and protective factors in adolescence

This study investigates the relationships among social isolation, psychological health, and protective factors in adolescents. Feelings of social isolation may influence psychological health in adolescents, but protective factors such as family connectedness, school connectedness, and academic achievement may also play a key role. The sample included 4,746 adolescents from 31 middle and high schools. Participants responded to 221 survey questions regarding peer relationships, psychological health, school connectedness, family relationships, and academic achievement. The findings revealed that social isolation was associated with an increased risk for depressive symptoms, suicide attempts, and low self-esteem. Protective factors influenced associations between social isolation and psychological health. Implications for prevention such as building healthy peer relationships, promoting family connectedness, and developing school-based interventions are discussed.     

The role of emotional elaboration in the creation of false memories

Two experiments employed an eyewitness suggestibility paradigm to examine the effects of emotional elaboration on the creation of false memories for suggested events. The results of both experiments converge in showing that reflectively elaborating on the emotional consequences of suggested events increases both false belief and false memory in having witnessed the suggested events. Moreover, the results also showed that emotional elaboration leads to higher false memory than other types of meaningful elaboration, thus providing evidence that the emotional content of the elaboration plays a role in promoting false memory development. The results have several real‐world implications for forensic and therapeutic interviews. Copyright © 2008 John Wiley & Sons, Ltd.     

Construct Validity of the Perceived Criticism Measure

The construct validity of the Perceived Criticism Measure (PCM) was examined in 2 studies. In Study 1, 50 community couples participated in problem-solving interactions after which they rated interaction-specific perceived criticism and their criticism of their spouses. In addition, they provided ratings of perceived criticism for their relationship overall and completed measures of psychopathology and marital satisfaction. For both husbands and wives, convergent validity was demonstrated by moderate-to-large correlations between the PCM and spouses' own ratings of their criticism for both general and interaction-specific perceived criticism. In Study 2, 37 patients with obsessive-compulsive disorder and their spouses participated in problem-solving interactions and provided ratings of marital satisfaction and general perceived criticism. Five untrained coders rated the interactions according to their own definitions of the relatives' destructive criticism of the patient. Their aggregated ratings proved strongly related to patients' PCM scores. Higher PCM scores were related to lower marital satisfaction in both Studies 1 and 2. The results of these studies are supportive of the convergent validity of the Perceived Criticism Measure. Evidence of discriminant validity was mixed.     

Thwarting the Need to Belong: Understanding the Interpersonal and Inner Effects of Social Exclusion

The need to belong is a powerful motivational basis for interpersonal behavior, and it is thwarted by social exclusion and rejection. Laboratory work has uncovered a destructive set of consequences of being socially excluded, such as increased aggressiveness and reduced helpfulness toward new targets. Rejected persons do, however, exhibit a cautious interest in finding new friends. Theory and intuition associate social exclusion with emotional distress, but laboratory research finds instead that the first response is a reduced sensitivity to pain and an emotional insensitivity that hampers empathy and may contribute to a variety of interpersonal behaviors. Self-regulation and intelligent thought are also impaired as a direct result of being rejected.     

Body dissatisfaction and body comparison with media images in males and females

This study examined the role of media body comparison as a mediator of the relationships between psychological factors and sociocultural pressures to be thin and body dissatisfaction in both females and males. Participants were 1,386 females (mean age = 19.37 years) and 1,130 males (mean age = 19.46) from diverse backgrounds who completed a self-report questionnaire. Path analysis was used to test a cross-sectional model in which media body comparison mediated the impact of self-esteem, depressive mood, parent dieting environment, friend dieting, TV exposure, magazine message exposure, weight teasing and body mass index (BMI) on body dissatisfaction. In females, media body comparison partially or fully mediated relationships between self-esteem, depressive mood, friend dieting, magazine message exposure and BMI, and body dissatisfaction. In males, media body comparison was not a significant predictor of body dissatisfaction. This research particularly highlights the need to further examine processes that are involved in the development of body dissatisfaction in males.     

Human search procedures and the use of expert systems

Four experiments are reported. These experiments compare the effects of two different forms of machine advice on performance on a complex search task. The task involves determining which of a set of factories is responsible for polluting a river by testing the river for the presence or absence of various pollutants. Subjects either receive a suggestion as to which pollutant they should test for on each go, or following testing for a pollutant they are told which of the factories could possibly be polluting the river at that stage, or they receive a combination of the two forms of advice. The experiments show that suggesting to subjects which pollutant they should test for on each go is of no benefit, whereas providing a list of possible factory names after testing for each pollutant significantly benefits performance. Only subjects who receive both types of advice simultaneously, however, maintain an improved performance level when the advice is withdrawn. This research was supported by the Alvey Directorate. Mr. E.C. Portman of ICL, West Gorton, acted as “industrial uncle” to the project.     

Brand character as a function of brand loyalty

This study investigated the relationship between self-image, brand image, and brand loyalty by asking whether people use products to enhance self-image. Subjects described themselves on an adjective checklist, then listed product brands to which they consider themselves loyal or not loyal. One month later, using the same adjective checklist, subjects described the type of person who would buy a particular brand to which they are loyal and a brand to which they are not loyal for both gender and non-gender related products. Significant differences between the two groups and a high correlation between self and product user ratings, were found.     

Household family structure and children's aggressive behavior: A longitudinal study of urban elementary school children

The relationship between contemporary household family structures at fourth-grade and sixth-grade parent- and teacher-rated aggression was examined in an epidemiologically defined population of urban school children. The relationship between family structure and aggression varied by child gender and by parent and teacher ratings in the home and school, respectively. After taking into account family income, urban area, and fourth-grade aggressive behavior, boys in both mother—father and mother—male partner families were significantly less likely than boys in mother-alone families to be rated as aggressive by teachers. No significant relations between family structure and teacher- or parent-rated aggression were found for girls.This work was supported by the following National Institute of Mental Health (NIMH) grants: Epidemiologic Prevention Center for Early Risk Behavior P50 MH38725; Periodic Outcome of Two Preventive Trials RO1 MH42968; and a Postdoctoral Training Program 2T32MH18834-06A1.
