A description is presented of the development of a new scale to measure social support which is called the Significant Others (SOS) Scale. The scale measures different functional resources of social support that may be provided by a number of significant role relationships within an individual's social network. Preliminary results from a sample of mature students show that the scale has good six-month test--retest reliability, and significantly distinguishes between depressed and nondepressed respondents. Details of a short form of the scale currently being developed are also presented.

SynopsisThe research presented in this paper examined the relationship between the presence of childhood behaviour problems and the rate of life events and difficulties in early adult life. Data are presented from a 20 year follow-up study of a sample of inner London school children first studied when they were aged 10. The key finding was that emotional or behavioural disturbance in childhood was associated with a marked increase in the rate of severely negative events and difficulties some two decades later. This increase was only obtained for stressors with severe negative impact of the type shown in previous investigations to be associated with the onset of psychiatric disorder. Additional results demonstrated that this main finding could not be accounted for by stressors that were a result of adult psychiatric disorder, by the respondent's own behaviour, or by continuing association with the family of origin. The need for a lifespan developmental approach to the well-established stressor-illness link is discussed.

The development of a new standardised investigator-based interview, PACE (Psychosocial Assessment of Childhood Experiences), for the assessment of acute life events and long-term psychosocial experiences is described. An application of PACE to a sample of 84 children referred to psychiatric clinics and 22 general population controls, is presented. Reliability was assessed using a separate clinic sample of 15 child-parent pairs. The findings showed that PACE has satisfactory reliability and discriminant validity.

A description of a social-cognitive theory of depression is presented which combines the concepts of mental models, personal goals and social roles. An analysis is made of how a number of proposals about the onset of depression can be summarized as the loss of a valued goal or social role in an individual who has few other sources of self-worth. In subsequent sections, limitations of the theory are outlined, and the relationship between the present theory and other theories of depression is briefly considered.

U fenbrenner & Crouter, 1983) has contributed in many important ways to our understanding of psychological processes, but probably his most important message has been the necessity of considering development in its social context. Growth takes place in a social milieu, and it will, therefore, be influenced by a person's interactions and transactions with that milieu, as well as by within-the-individual organismic factors. Bronfenbrenner's portrayal of these processes has been put in ecological terms: a biological concept. One implication is that the impact of particular experiences may vary according to their social context and according to their psychological meaning in relation to a person's previous background and experiences, as well as current circumstances. This consideration focuses on the likely operation of interactions of various sorts, including the possibility that individuals differ in their susceptibility to specific environmental factors. Such interactions are widespread in biology and medicine (Rutter h Pickles, 1991), and they are likely to be so in psychological development, although so far there have been few investigations using methods likely to reveal them.

Three cognitive approaches to depression are reviewed in terms of recent advances in cognitive psychology. The approaches considered are those based on associative networks, schemata, and explanatory styles. It is argued that each of these approaches has significant limitations that can be overcome if they are replaced by the theory of mental models (Johnson-Laird, 1983). A number of specific advantages for this theory are outlined and the basis is provided for a new cognitive approach to depression.

SYNOPSISResearch on the role of life events in the onset of depression has suggested that certain vulnerability factors can increase the risk of disorder in the face of a threatening event. The role of vulnerability factors to increase the likelihood of severs events occurring in the first place has remained largelu unexplored. The vulnerability factor which has received the most attention is a lack of social support, particularly lack of a confiding relationship with a husband for women. A reanalysis of a number of published studies is undertaken; this shows that there is a positive relationship between lack of intimacy and the occurrence of adversity. The implications of this finding are briefly discussed, with emphasis on the need for a life-span developmental perspective in future life events research.
