Dysphoric adolescents' causal explanations and expectancies for approach and avoidance goals.

Relatively little research has studied emotional disturbance from a motivational perspective. The current study aimed to investigate personal goal systems at different levels of analysis, namely, personal goals, associated causal explanations and goal expectancies, as a function of dysphoria. Dysphoric (n = 28) and non-dysphoric (n = 28) adolescents (16-18-yr-olds) selected from a larger school sample completed tasks that measured number of approach goals and avoidance goals, causal explanations for goals, and perceived likelihood and control estimates for idiographic goals. As predicted dysphoric adolescents, relative to controls, generated a combination of more avoidance goals and fewer approach goals, and thought of more reasons that explain why goals would not be achieved and fewer reasons that explain why goals would be achieved (irrespective of goal type), and considered avoidance goal outcomes as more likely to occur and approach goal outcomes as less likely to occur. In addition, dysphoric adolescents anticipated less personal control in implementing their goals than controls. Overall, the data identified distinct personal goal systems that function differently in dysphoric and non-dysphoric adolescents.

Goal pursuit, goal self-concordance, and the accessibility of autobiographical knowledge.

Recent theory suggests that personal goals influence the accessibility of autobiographical knowledge. We suggest that this effect is moderated by goal self-concordance: the extent to which a goal is pursued for autonomous rather than controlling reasons. Cueing paradigms were used to measure the accessibility of autobiographical knowledge relating to (i) goals that participants were and were not pursuing, and (ii) currently pursued goals that were high and low in self-concordance. As predicted, autobiographical knowledge relating to currently pursued goals was more accessible than autobiographical knowledge relating to non-pursued goals. General event knowledge relating to self-concordant goals was more accessible than general event knowledge relating to non-self-concordant goals, but a corresponding relationship did not emerge for event-specific knowledge.

Future-directed thinking and depression in relapsing-remitting multiple sclerosis.

BACKGROUND: Research has shown that depression is associated with a view of the future characterized by reduced anticipation of future positive experiences, but not necessarily increased anticipation of future negative experiences. The aim of the present study was to investigate how participants with relapsing-remitting multiple sclerosis (MS) anticipated their future in terms of positive and negative events. DESIGN: A mixed design compared three groups of participants on a measure of future thinking using an adapted verbal fluency paradigm. METHODS: Depressed MS participants (N=14), non-depressed MS participants (N=28) and healthy control participants (N=26) were assessed on their ability to generate future positive and negative experiences. A content analysis was also conducted on the responses generated by the MS depressed and MS non-depressed groups according to whether or not they were related to MS. RESULTS: The MS depressed group anticipated significantly fewer future positive events than the healthy control group and the MS non-depressed group. The three groups did not differ in the total numbers of anticipated future negative events, though the MS depressed group did anticipate a significantly higher proportion of MS-related negative events. CONCLUSIONS: Like depressed but physically healthy individuals, the MS depressed group was characterized by a lack of positive thoughts about the future, rather than an increased number of negative thoughts. The clinical implications of these findings are discussed along with recommendations for future research.

Hopelessness and positive and negative future thinking in parasuicide.

OBJECTIVES: Hopelessness about the future is a key element in suicidal behaviour. The aim of the present study was to examine possible components of hopelessness, in particular, to contrast positive and negative future thinking and to examine separately number, expectancy, and value of anticipated positive and negative future experiences. DESIGN: A correlational design. METHOD: Repeat parasuicide patients (N = 441) were administered the Beck Hopelessness Scale, the Hospital Anxiety and Depression Scale and the future thinking task, a measure of future positive and negative thinking that assesses number, perceived likelihood, and perceived value of anticipated future positive and negative events. RESULTS: Consistent with predictions, hopelessness correlated more strongly with lack of positive thoughts about the future than it did with presence of negative thoughts. Both positive and negative future thinking showed a relationship to hopelessness over and above their relationships to depression (positive future thinking) and anxiety (negative future thinking). Number and likelihood of positive events and likelihood and value of negative events showed both simple and partial relationships to hopelessness. Number of negative events related to hopelessness but only after the other future thinking variables had been controlled for and value of positive events no longer related to hopelessness after controlling for the other variables. CONCLUSIONS: Hopelessness about the future in suicidal individuals is a multi-faceted construct but lack of positive future thinking is more important than presence of negative future thinking.

Retrospective and prospective cognitions in adolescents: anxiety, depression, and positive and negative affect.

Research with anxious and depressed adults has suggested that anxiety is related to an increased anticipation of both negative memories and negative expectancies whereas depression is related to a reduction in positive memories and expectancies. The present study examined whether anxiety and depression in 123 school-aged adolescents would show the same pattern. Small groups completed a memory and future thinking task in which they were asked to generate future and past, positive and negative events. Adolescents with higher levels of depression and those with higher levels of anxiety reported significantly more negative events relative to controls, but neither group generated fewer positive events. The results provide support for the involvement of cognitions in mood disturbance although do not support the idea that these cognitions are different in anxiety and depression.

Personality disorder and future-directed thinking in parasuicide.

Parasuicide patients have been found to lack positive expectations for the future. The aim of the present study was to look at variations in this lack of positive future-thinking as a function of personality status. A sample (N = 442) of repeat parasuicide patients was assessed on positive and negative future-thinking and the presence of personality disorder or personality difficulty. Those with a Cluster B personality disorder (borderline or dissocial) were significantly lower in positive future-thinking than those with no Cluster B symptoms or those with Cluster B personality difficulty. Neither Cluster A nor Cluster C symptomatology was related to positive future-thinking. Negative future-thinking was not significantly related to any type of personality disorder or difficulty. The results are interpreted as evidence of the importance of personality status in influencing positive future-thinking and gives some indications of why those with Cluster B personality disorder have such high rates of recurrent self-harm.

Beliefs about alcohol among UK Jews and Protestants: do they fit the alcohol-depression hypothesis?

BACKGROUND: Some research has suggested that Jews drink less alcohol than other cultural groups, and may have different beliefs about its use. Differences in beliefs about alcohol, and different patterns of use, may play a role in accounting for cultural and gender variations in depression prevalence. Alcohol may act as an escape route from depression, thus deflating depression rates in certain groups of people, in particular, men from Protestant backgrounds. METHODS: Self-reported use and beliefs about alcohol were assessed in a UK sample of 70 Jews and 91 Protestants, including non-practising people of Jewish and Protestant background. The effects of religious group and of gender on measures of alcohol behaviour and beliefs were examined. RESULTS: Some differences were found between Jews and Protestants. Jews had less favourable beliefs about alcohol and drank less than Protestants. More importantly, and in line with our hypotheses, there were gender differences in Protestants but not Jews with respect to some beliefs about alcohol and actual use of alcohol. CONCLUSIONS: The study goes some way in supporting the notion that religious-cultural and gender differences in beliefs and behaviour towards alcohol may contribute to religious-cultural and gender differences in rates of depression.

The suicide beliefs of Jews and Protestants in the UK: how do they differ?

It has been suggested that Protestant culture has become more tolerant towards suicide in the previous century, while Jewish culture has traditionally not condoned suicide. There have been reports that suicide rates are somewhat lower among Jews than among people of Protestant background. We asked whether there were differences between Jews' and Protestants' beliefs about suicide that might relate to these suggestions and reports. Beliefs about suicide were assessed from the Reasons For Living Inventory (RFL), and with questions about the acceptability of suicide in some circumstances. Self-reported suicide ideation and attempts were also assessed. Some religious-cultural differences were found in beliefs about suicide, but not with regard to ideation and behavior. We discussed the relations between differences in belief, and reported differences in suicide prevalence, and suggested that most of the belief differences were consistent with reported patterns of prevalence. Notably, Jews believed more strongly than Protestants that moral-religious objections to suicide were reasons for living, and that suicide was less acceptable in certain circumstances.
