Positive and negative daily events, perceived stress, and alcohol use: A diary study.

Using daily diary methodology, the authors examined over 60 days the within-person associations among positive and negative daily experiences, perceptions of stress, desire to drink, and alcohol consumption in a sample of 83 regular drinkers. Multilevel regression analyses indicated that days on which individuals reported more positive and negative nonwork events were also days they reported higher levels of desire to drink and actual consumption. Days on which individuals reported more negative work events were also days they reported a greater desire to drink, and days on which individuals reported more positive and negative health events were also days they reported lower levels of desire to drink and actual consumption. Weak evidence was found for the mediating effects of perceived stress in these associations. Several of the within-person associations varied as a function of gender, neuroticism, and drinking to cope; no moderating effects were found for extraversion.

Attributions for negative life events and depression: The role of perceived control.

Although perceptions of control occupied a central role in the development of learned helplessness theory, recent helplessness research has not considered controllability judgments when relating attributions to depression. Supporting the importance of this construct, the research discussed in this article found evidence that judgments of control interact with other attributions in predicting depression. Specifically, in a prospective study of stress and well-being in adolescence, internal, stable, and global attributions for negative events attributed to uncontrollable causes were found to be positively related to increases in depression (as predicted by the reformulated helplessness theory), but internal and global attributions for negative events attributed to controllable causes were found to be inversely related to increases in depression. The discussion considers the implications of the findings for understanding the nature of the relation between attributions for naturally occurring life events and depression.

Social ties and susceptibility to the common cold

OBJECTIVE: To examine the hypothesis that diverse ties to friends, family, work, and community are associated with increased host resistance to infection. DESIGN: After reporting the extent of participation in 12 types of social ties (eg, spouse, parent, friend, workmate, member of social group), subjects were given nasal drops containing 1 of 2 rhinoviruses and monitored for the development of a common cold. SETTING: Quarantine. PARTICIPANTS: A total of 276 healthy volunteers, aged 18 to 55 years, neither seropositive for human immunodeficiency virus nor pregnant. OUTCOME MEASURES: Colds (illness in the presence of a verified infection), mucus production, mucociliary clearance function, and amount of viral replication. RESULTS: In response to both viruses, those with more types of social ties were less susceptible to common colds, produced less mucus, were more effective in ciliary clearance of their nasal passages, and shed less virus. These relationships were unaltered by statistical controls for prechallenge virus-specific antibody, virus type, age, sex, season, body mass index, education, and race. Susceptibility to colds decreased in a dose-response manner with increased diversity of the social network. There was an adjusted relative risk of 4.2 comparing persons with fewest (1 to 3) to those with most (6 or more) types of social ties. Although smoking, poor sleep quality, alcohol abstinence, low dietary intake of vitamin C, elevated catecholamine levels, and being introverted were all associated with greater susceptibility to colds, they could only partially account for the relation between social network diversity and incidence of colds. CONCLUSIONS: More diverse social networks were associated with greater resistance to upper respiratory illness.     

Intraindividual and interindividual analyses of positive and negative affect: Their relation to health complaints, perceived stress, and daily activities.

I examined correlates of Negative Affect (NA) and Positive Affect (PA) through both within- and between-subjects analyses. Eighty subjects completed a daily questionnaire for 6-8 weeks. Each day they rated (a) their mood, (b) the extent to which they suffered from various minor physical problems, (c) their level of stress, (d) the time they spent socializing, and (e) whether or not they had exercised. Subjects also completed several trait tests measuring their general affective level, frequency of health problems, and social tendencies. A between-subjects analysis showed the expected pattern: Level of physical complaints and perceived stress were correlated with individual differences in NA but not in PA, whereas social indicators and frequency of exercise were related only to PA. The within-subjects results generally exhibited a similar pattern: Social activity and exercise were more strongly related to PA, whereas perceived stress was highly related to NA. However, the most significant finding was that, contrary to prediction, health complaints were as strongly related to intraindividual fluctuations in PA as in NA. Possible interpretations of the observed correlates of NA and PA are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Objective and subjective socioeconomic status and susceptibility to the common cold.

Objective: We ask whether subjective socioeconomic status (SES) predicts who develops a common cold when exposed to a cold virus. Design: 193 healthy men and women ages 21-55 years were assessed for subjective (perceived rank) and objective SES, cognitive, affective and social dispositions, and health practices. Subsequently, they were exposed by nasal drops to a rhinovirus or influenza virus and monitored in quarantine for objective signs of illness and self-reported symptoms. Main Outcome Measures: Infection, signs and symptoms of the common cold, and clinical illness (infection and significant objective signs of illness). Results: Increased subjective SES was associated with decreased risk for developing a cold for both viruses. This association was independent of objective SES and of cognitive, affective and social disposition that might provide alternative spurious (third factor) explanations for the association. Poorer sleep among those with lesser subjective SES may partly mediate the association between subjective SES and colds. Conclusions: Increased Subjective SES is associated with less susceptibility to upper respiratory infection, and this association is independent of objective SES, suggesting the importance of perceived relative rank to health.

Cognition and life stress in depression: Cognitive factors and the definition, rating, and generation of negative life events.

The relationship between cognitive factors and different conceptualizations and measures of life stress poses important questions for contemporary theories of depression. The authors examined whether cognitive factors (dysfunctional attitudes and attributional style) are related to the definition, rating, and generation of negative life events. Life events were assessed with both subjective self-report and more objective interview-based methods in endogenously depressed outpatients. The results partially support the hypothesis that cognitive factors are related to definition and severity ratings of self-report measures of particular types of life events. These relationships held primarily for achievement, as compared with interpersonal, events. The results also support the hypothesis that elevated scores on measures of cognition are associated with the number of objectively defined events occurring prior to the onset of depression, suggesting that some patients may generate the life events that in turn may initiate a depressive episode.

Resilience-as-process: Negative affect, stress, and coupled dynamical systems.

Resilience is often considered both a trait and a process. The current study proposes a new way to conceptualize resilience-as-process based on dynamical systems modeling, which allows researchers to capture the process of stress management in real time. Coupled damped linear oscillator models succinctly describe daily stress and negative affect in terms of developmental forces (e.g., velocity, acceleration). Models were fit to 56-day daily response data from 42 aging adults (Mage = 78.8 years; SDage = 6.6 years) to observe and understand linkages between daily stress and affect. It was speculated that individuals with greater resilience would experience stress as less coupled to changes in negative affect (less stress reactivity), and would recover their affective equilibrium more quickly following a given exogenous stressor (greater stress recovery). To identify resilience resources related to reliable interindividual differences in coupling and damping between stress and negative affect, we examined possible protective factors. Aspects of personality and social support predicted both the strength and nature of this coupling, such that higher levels of these resources resulted in greater protection from the cost to negative affect from stress, as observed in damping of negative affect and decreased coupling between systems.

Negative affective states and the motivated retrieval of positive life events: The role of affect acknowledgment.

People sometimes cope with negative moods by retrieving positive memories, thus exhibiting a mood-incongruency effect. It was proposed that this type of motivated recall involves a 2-stage process: Individuals must first openly acknowledge their negative moods before they will adopt a recall strategy to alleviate their distress. Individual differences in affect acknowledgment (repression-sensitization, meta-mood beliefs, etc.) should therefore predict the occurrence of mood-incongruent recall. The results of 3 studies supported this hypothesis. Studies 1 and 2 revealed that sensitizers (but not repressors) reported more negative affect, and hence recruited more positive memories, after a negative mood induction than after a neutral mood induction. In Study 3, the same recall effects emerged when a more direct measure of affect acknowledgment, meta-mood beliefs, was used as a moderator.

Negative affectivity and the reporting of stressful life events.

Replicated D. T. Lykken's study (see record 1968-18058-001) to resolve the conflict between the findings of S. R. Maddi et al (see record 1987-22446-001) and those of D. H. Schroeder and P. T. Costa (see record 1984-23643-001) regarding the impact of negative affectivity (NA; i.e., neuroticism) contaminated life event items on observed life event–illness relationships. Among 330 managers and professionals, NA-contaminated items correlated significantly with 3 measures of well-being (depression, life satisfaction, and physical symptoms). In 2 of 3 cases, correlations between contaminated items and well-being measures were significantly different from correlations between uncontaminated items and well-being indicators. Prior life event–well-being findings may be inflated considerably by the use of NA-contaminated events. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A little bit louder now: Negative affect increases perceived loudness.

Traditionally, perception was considered to be an encapsulated process that was unaffected by top-down processes like affect. Recent work in vision draws this framework into question by showing that changes in the affective state of the perceiver can impact many different aspects of visual perception. Here, we extend the relationship between affect and perception into another perceptual modality: audition. Participants were induced into a negative or neutral mood by writing about a frightening or neutral experience in their past. They then listened to a series of short, neutral tones (320 and 640 ms) and rated the loudness and duration of the tones. Participants in a negative mood rated the tones as significantly louder, but not longer, than participants in a neutral mood, suggesting that the difference between the groups was perceptual rather than just a response bias. This research shows for the first time that the role of affect in perceptual processes may be more pervasive than previously considered.

Negative life events and time to recovery from episodes of bipolar disorder.

The authors of the current study examined the impact of severe negative life events on time to recovery from episodes of bipolar disorder. Although negative life events have been shown to influence relapse in bipolar disorder, research has not focused on life events and recovery in bipolar disorder. The authors recruited 67 individuals with bipolar disorder during hospitalization and conducted monthly assessments for at least 1 year. Individuals with severe negative life events took more than 3 times as long to achieve recovery as those without severe life events, and the impact of life events was not mediated by medication compliance. These results reveal that the psychosocial environment may play a much larger role in the course of bipolar disorder than previous biological models have suggested.

Positive affect, negative affect, and social interaction.

Two studies explored the relations of positive and negative affect (PA and NA) to social interaction. In Study 1, unacquainted dyads were surreptitiously videotaped as they participated in a 6-min interaction. Participants then evaluated the quality of the interaction. Independent observers also rated the videotaped interactions. Trait PA was positively related to both participant and observer evaluations of interaction quality. In Study 2, undergraduates kept diaries of their social interactions for 1 week, PA was again related to interaction quality. Both PA and NA were positively related to the number of interactions in which participants engaged, and the amount of time spent engaged in social contact, although different types of social encounters produced these relations.

Types of stressors that increase susceptibility to the common cold in healthy adults.

Two-hundred seventy-six volunteers completed a life stressor interview and psychological questionnaires and provided blood and urine samples. They were then inoculated with common cold viruses and monitored for the onset of disease. Although severe acute stressful life events (less than 1 month long) were not associated with developing colds, severe chronic stressors (1 month or longer) were associated with a substantial increase in risk of disease. This relation was attributable primarily to under- or unemployment and to enduring interpersonal difficulties with family or friends. The association between chronic stressors and susceptibility to colds could not be fully explained by differences among stressed and nonstressed persons in social network characteristics, personality, health practices, or prechallenge endocrine or immune measures.

Negative life events, coping responses, and combat-related psychopathology: A prospective study.

This study examined the relations of life events and coping responses to combat-related psychopathology among 255 Israeli soldiers who suffered a combat stress reaction episode during the 1982 Lebanon War. Follow-ups 1 and 2 years after their participation in combat found (a) significant effects of psychopathology at 1 year after the war on the occurrence of negative life events and the choice of coping responses during the following year; (b) unique and significant effects of negative life events and coping responses on psychopathology at 2 years after the war; (c) a significant interaction between life events and coping responses on psychopathology; and (d) a significant indirect effect of negative life events on psychopathology via the choice of coping responses. Theoretical implications of the findings were discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Nicotine, negative affect, and depression.

Depression, whether conceptualized as a trait, symptom, or as a diagnosable disorder, is overrepresented among smokers. Depressed smokers appear to experience more withdrawal symptoms on quitting, are less likely to be successful at quitting, and are more likely to relapse. This article documents these relationships and explores several potential links between smoking and depression. The potential efficacy of antidepressant therapy, cognitive-behavioral therapy, and nicotine replacement therapy for smokers with depressive disorders or traits is discussed. Clinical implications and the role of patient treatment matching are also discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Negative life events, marital interaction, and the longitudinal course of newlywed marriage

Life events and problem-solving behavior were examined relative to longitudinal change in depressive symptoms and marital adjustment over 18 months in 60 newlywed couples. Spouses' problem-solving behavior moderated, but did not mediate, the relationship between life events and adjustment. Some behaviors contributed to spouses being more resilient to life events, and some behaviors made spouses more vulnerable. In particular, wives' anger facilitated their adjustment to major and interpersonal events such that their depressive symptoms declined and their marital satisfaction increased. Husbands' humor contributed to marital instability when spouses reported more major events. The results further specify the vulnerability-stress-adaptation model of marriage and expand on the role of behavior in marriage.     

Response biases and the relation between negative life events and psychological symptoms.

Investigated whether reporting biases can account for the correlation between negative life events and subclinical psychological symptoms. 73 undergraduates each brought a close friend to the experiment. Ss completed the Beck Depression Inventory, the Brief Symptom Inventory, the Marlowe-Crowne Social Desirability Scale, and a college student life events schedule. Friends were asked to report about life events experienced by the Ss. Findings did not support an S reporting bias associated with social desirability, depression, or symptoms. For one of the life events scales, depression was significantly associated with a higher rate of agreement between Ss and friends as to which negative events occurred to Ss. There were significant correlations between symptom and depression measures and life events measures that were free of S-reporting biases (Ss' negative life events reported by both Ss and their significant others, as well as Ss' negative life events as reported by significant others alone). Data suggest that response biases may not be able to account for the relation between negative events and psychological symptoms. It is contended, however, that the hypothesis that negative life events play a significant role in symptom development remains plausible.

Coping with perceived peer stress: Gender-specific and common pathways to symptoms of psychopathology.

This study investigated gender differences in the moderating and mediating effects of responses to stress on the association between perceived peer stress and symptoms of psychopathology. A sample of 295 middle school students (63.7% female; Mage = 12.39 years, SD = 0.99) completed self-report surveys on stress, coping, and behavioral problems. Involuntary responses to stress (e.g., physiological arousal, intrusive thoughts, impulsive action) mediated the association between perceived stress and anxiety/depression and aggression for girls and for boys. Disengagement coping (e.g., denial, avoidance) partially mediated the association between peer stress and anxiety/depression for boys and for girls. In contrast, disengagement coping mediated the association between peer stress and overt aggression for boys only. Finally, engagement coping (e.g., problem solving, emotion regulation, cognitive restructuring) buffered the indirect effect of peer stress on symptoms of psychopathology for girls only. Implications for prevention and intervention efforts are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Generalized self-efficacy, self-esteem, and negative affect.

In order to help resolve the ongoing debate about the relationship between and the functions of self-esteem and generalized self-efficacy (GSE), the authors tested the hypotheses that GSE predicts future self-esteem and that self-esteem predicts unique incremental variance in future negative affect. Measures of these three constructs were administered to two samples of undergraduates (N = 160 and N = 75) twice over five-six weeks. Time 1 GSE accounted for significant variance in Time 2 self-esteem in both studies, 1.6% of the variance in Study 1 and 4.6% of the variance in Study 2, after controlling for Time 1 self-esteem. Time 1 self-esteem did not predict Time 2 GSE in either study. Self-esteem accounted for significant variance in negative affect in Study 1. Results suggest that GSE and self-esteem are distinct, that GSE may play a role in the development of self-esteem, and that self-esteem may help shape negative affect.
