The development of an adequate assessment instrument is a necessary prerequisite for social psychological research on loneliness. Two studies provide methodological refinement in the measurement of loneliness. Study 1 presents a revised version of the self-report UCLA (University of California, Los Angeles) Loneliness Scale, designed to counter the possible effects of response bias in the original scale, and reports concurrent validity evidence for the revised measure. Study 2 demonstrates that although loneliness is correlated with measures of negative affect, social risk taking, and affiliative tendencies, it is nonetheless a distinct psychological experience.

Among married couples, the effect of the controllability of stressful events was tested as a predictor of the type of social support communications provided and preferred. Sixty married individuals disclosed stressful events to their spouse. Controllability of the stress was rated by observers. The Social Support Behavior Code was used to assess the frequency with which each of five types of social support was provided by the spouse. Action-promoting support (information) was provided most frequently when the stressed person had high control over the event. Of the five types of support communications assessed, only information was evaluated differently in high- and low-controllable situations. Both controllability by the support recipient and controllability by his or her spouse were relevant to support evaluations. Results provide limited support for the optimal matching model proposed by Cutrona and Russell (Cutrona, 1990; Cutrona & Russell, 1990).

Longitudinal links between perceived racial discrimination and later conduct problems and depressive symptoms were examined among 714 African American adolescents who were 10-12 years old at recruitment. Data were gathered 3 times over a 5-year period. Hypotheses were tested via latent curve modeling and multiple-group latent growth modeling. Increases in perceived discrimination were associated with increased conduct problems and depressive symptoms. This association was weaker when youths received nurturant-involved parenting, affiliated with prosocial friends, and performed well academically. For conduct problems, the association was stronger for boys than for girls; for depressive symptoms, no gender differences emerged. The findings thus identify contextual variables that moderate the contribution of perceived discrimination to African American youths' adjustment.

A model of maternal postpartum depression was tested in which difficult infant temperament was construed as a stressor and supportive interpersonal relationships were construed as a protective resource. It was hypothesized that both infant temperamental difficulty and level of social support would affect maternal depression through the cognitive mediation of perceived self-efficacy in the parenting role. Participants were 55 married women who were assessed during pregnancy and again 3 months postpartum. Infant temperament was assessed through observation, maternal crying records, and the Revised Infant Temperament Questionnaire. Results of a path analysis indicated that infant temperamental difficulty was strongly related to the mothers' level of postpartum depression, both directly and through the mediation of parenting self-efficacy. Consistent with predictions, social support appeared to exert its protective function against depression primarily through the mediation of self-efficacy. Both practical implications for identifying women at risk for postpartum depression and theoretical implications for understanding the mechanisms through which stressful events and social support affect adjustment are discussed.
