The independence of positive and negative affect.

Five studies, with 776 undergraduates and 34 33–85 yr old community residents, investigated the relation beween positive and negative affect. Instruments included the Rosenberg Self-Esteem Scale, Eysenck Personality Inventory, and 16PF. In Studies 1 and 2, positive feelings were remembered as being nearly independent of negative feelings in the past year, but the 2 types of affect were moderately negatively correlated for the past month. In Studies 3 and 5, Ss completed daily mood reports for 70 and 30 days, respectively. In Study 4, Ss completed 3-wk, daily, and moment mood reports and also filled out reports when they experienced strong emotions. The principal finding was that the relation between positive and negative affect differed greatly depending on the time frame. The strongest negative correlation between the 2 affects occurred during emotional times. The correlation decreased in a linear fashion as the time span covered increased logarithmically. It appears that positive and negative affect are independent in terms of how much people feel in their lives over longer time periods.

Intensity and frequency: Dimensions underlying positive and negative affect.

Research on emotions and several happiness scales suggests that positive and negative affect are strongly inversely correlated. However, work on subjective well-being indicates that over time, positive and negative affect are independent across persons. To reconcile this inconsistency, 2 dimensions are proposed for personal affective structure: the frequency of positive vs negative affect and the intensity of affect. In 3 studies, 68 undergraduates and 34 33–85 yr old community residents completed daily and momentary reports on their moods. In support of the intensity dimension, the correlations between positive and negative intensity were strong and positive in all 3 studies. The intensities of specific emotions across Ss were also highly correlated. Across the 3 studies the frequency and intensity of affect varied independently. Although average levels of positive and negative affect showed low correlations, this relation became strongly inverse when intensity was partialed out. Thus, the intensity dimension helps explain the relative independence of positive and negative affect. (29 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

On the independence of positive and negative affect.

Three separate but mutually compatible explanations are offered for N. M. Bradburn's (1969) finding that positive and negative affects are statistically independent: (1) In terms of a higher-order generalization, numbers of experienced desirable and undesirable episodes are generally uncorrelated. (2) The independence is a function of a response mode and scoring procedure that differ from those used elsewhere. (3) Short-term affective states are linked with more stable personality dispositions. 500 undergraduates served as Ss. Findings support each of these explanations: (a) Numbers of desirable and undesirable recent life events were statistically independent and correlated with positive and negative affect in the predicted manner. (b) Amending the response format from counting the number of positive and negative experiences to requiring reports of the proportion of time each was experienced yielded an intercorrelation of –.54 compared to –.01 in the original format. (c) Positive and negative affects were significantly associated with extraversion and neuroticism, respectively, but not with the other dispositional measure. Each explanation had value within 3 different conceptual and methodological frameworks. (27 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Diurnal cortisol secretion and 2-year changes in older adults' physical symptoms: The moderating roles of negative affect and sleep.

Objective: This study examined whether the association between cortisol secretion and changes in physical health symptoms would depend on other factors in a person's life. The authors expected that physical health effects would emerge particularly when cortisol disturbances co-occur in the context of high levels of trait negative affect or poor sleep. Design: Physical symptoms, diurnal cortisol secretion, affective tendencies, and sleep efficiency were assessed in a 2-yr longitudinal study of 184 older adults. Main Outcome Measure: Two-year changes in physical symptoms. Results: High cortisol levels were associated with increases in physical symptoms, but only among participants who experienced high negative affect and poor sleep. Conclusion: Elevated levels of cortisol secretion contribute to older adults' physical symptoms if they co-occur in the context of other emotional and behavioral problems. By contrast, cortisol disturbances may not influence physical symptoms among people who are emotionally well or engage in efficient sleep behaviors.

Origins and functions of positive and negative affect: A control-process view.

The question of how affect arises and what affect indicates is examined from a feedback-based viewpoint on self-regulation. Using the analogy of action control as the attempt to diminish distance to a goal, a second feedback system is postulated that senses and regulates the rate at which the action-guiding system is functioning. This second system is seen as responsible for affect. Implications of these assertions and issues that arise from them are addressed in the remainder of the article. Several issues relate to the emotion model itself; others concern the relation between negative emotion and disengagement from goals. Relations to 3 other emotion theories are also addressed. The authors conclude that this view on affect is a useful supplement to other theories and that the concept of emotion is easily assimilated to feedback models of self-regulation.

Compound caregiving: When lifelong caregivers undertake additional caregiving roles.

Objective: Lifetime parental caregivers of adults with intellectual disabilities (ID) may also become caregivers to other family members. This study investigated caregiver experiences of compound caregiving (i.e. additional caregiving roles) and its association with caregiver quality of life. Participants: Ninety-one older caregivers living with their adult son/daughter with ID were interviewed. Mean age of the caregivers was 60 years and their sons'/daughters' mean age was 29 years. Main Outcome Measures: Compound caregiving status, physical and mental health, life satisfaction, depressive symptomatology, and desire for alternative residential placement for their co-residing son/daughter. Results: Thirty-four (37%) reported being current compound caregivers to an additional care recipient, predominantly a mother, father, or spouse. Caregivers averaged 39 hours per week fulfilling their primary caregiving tasks, an additional 12 hours per week on the compound caregiving role, and the median duration of compound caregiving was 3 years. Compared with the non-compound caregivers, the compound caregivers had increased desire to place their son/daughter into residential care, though no group differences were apparent in life satisfaction, depressive symptomatology, physical health, or mental health. The most problematic issues reported by compound caregivers were having little personal time and a lack of adequate help from others. Conclusion: Compound caregiving was often experienced, and may galvanize these lifetime caregivers to start making future plans for their sons/daughters. Future research is warranted to refine more homogeneous groupings of compound caregivers, who may be at greater risk for adverse outcomes.

Temporal profiles of physical health in family members of heart transplant recipients: Predictors of health change during caregiving.

Examined patterns of change in the physical health and well-being of 133 family caregivers to heart transplant recipients during the 1st yr after transplant. Ss were assessed at 2, 7, and 12 mo after transplant. Cluster analysis was used to identify temporal profiles reflecting unique patterns of change in the direction and nature of Ss' physical health; their temporal profiles showed either (a) a worsening of general medical condition (MC), with weight gain (14% of Ss); (b) worsening MC with weight loss (15%); (c) weight gain with stable MC (41%); (d) weight loss with slightly improving MC (21%); or (e) worsening health perceptions with relatively little objective evidence of MC change or weight (8%). Subsequent multivariate analyses indicated that Ss' characteristics measured at baseline and reflecting caregiving burden, coping styles, demographics, and health history reliably predicted membership in the pattern-of-health-change groups. Among the findings, Ss who showed a pattern of MC decline with weight loss had a poorer health history and weaker coping styles (lower mastery and higher use of avoidance coping) than other Ss. Ss who experienced MC decline with weight gain had the greatest levels of caregiver burden. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Development and validation of brief measures of positive and negative affect: The PANAS scales.

In recent studies of the structure of affect, positive and negative affect have consistently emerged as two dominant and relatively independent dimensions. A number of mood scales have been created to measure these factors; however, many existing measures are inadequate, showing low reliability or poor convergent or discriminant validity. To fill the need for reliable and valid Positive Affect and Negative Affect scales that are also brief and easy to administer, we developed two 10-item mood scales that comprise the Positive and Negative Affect Schedule (PANAS). The scales are shown to be highly internally consistent, largely uncorrelated, and stable at appropriate levels over a 2-month time period. Normative data and factorial and external evidence of convergent and discriminant validity for the scales are also presented. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Erotica and aggression: The influence of sexual arousal, positive affect, and negative affect on aggressive behavior.

95 male college students who had never taken a psychology course were first either angered or not angered by a confederate of the experimenter and were then ostensibly given an opportunity to aggress against the confederate by means of electric shock. Prior to aggressing, Ss were shown 1 of 4 sets of stimuli chosen to effect a factorial variation in the intensity of positive sexual arousal (high, low) and negative affect (high, low) elicited by exposure to such material. In addition, 1 group of angered Ss (no-exposure control) was included who did not view any of the 4 sets of stimuli prior to being given an opportunity to aggress. Results indicate that exposure to affectively positive erotic stimuli significantly reduced retaliatory behavior by angered males to a level below that exhibited by Ss exposed to neutral stimuli and by those in the no-exposure control group. In contrast, relative to baseline controls, Ss' exposure to erotic stimuli that were reported to be disgusting and unpleasant slightly enhanced subsequent aggressive behavior. Several possible mechanisms (e.g., attentional shifts, incompatible responses, cognitive labeling) are discussed in relation to the results.

Subsyndromal unipolar and bipolar disorders: Comparisons on positive and negative affect.

The authors examined the mood patterns of young adults with cyclothymia, intermittent depression, or no affective disorder in a nonclinical population. In a conceptual replication and extension of R. A. Depue et al. (see PA, Vol 67:1362, Study 5), participants completed a trait measure of mood and then completed daily mood ratings for 28 days. Individuals in the intermittent depression and cyclothymia groups were characterized by high levels of negative affect on trait and daily ratings. Both groups were also characterized by high variability of negative affect across days. Individuals with cyclothymia reported higher levels of trait and daily positive affect than individuals with intermittent depression and also exhibited high between-day variability on positive affect. Similarities and differences with R. A. Depue et al. are described and the results are discussed in terms of the common and differentiating features of the subsyndromal affective disorders.

The effect of age on positive and negative affect: A developmental perspective on happiness.

The effect of age on happiness, as defined by positive and negative affect, was examined in a survey of 2,727 persons of a broad age range (25–74) conducted by the MacArthur Foundation Research Network on Successful Midlife Development. The age–affect association was examined, controlling for a host of sociodemographic, personality, and contextual influences. Among women, age was related to positive affect nonlinearly but was unrelated to negative affect. Among men, age interacted with 2 key variables in predicting affect: extraversion and marital status. These findings lend support to recent life span theories of emotion and indicate that personality, contextual, and sociodemographic variables, as well as their interactions, are all needed to fully understand the age–affect relationship.

On the bipolarity of positive and negative affect

Is positive affect (PA) the bipolar opposite of, or is it independent of, negative affect (NA)? Previous analyses of this vexing question have generally labored under the false assumption that bipolarity predicts an invariant latent correlation between PA and NA. The predicted correlation varies with time frame, response format, and items selected to define PA and NA. The observed correlation also varies with errors inherent in measurement. When the actual predictions of a bipolar model are considered and error is taken into account, there is little evidence for independence of what were traditionally thought opposites. Bipolarity provides a parsimonious fit to existing data.     

The acute effects of nicotine on positive and negative affect in adolescent smokers.

Although adolescent cigarette smoking remains a critical public health concern, little is known about the reinforcing mechanisms governing smoking in this vulnerable population. To assess predictions derived from both positive and negative reinforcement models of drug use, the authors measured the acute effects of nicotine, as administered via tobacco cigarettes, on both positive and negative affect in a group of 15- to 18-year-old smokers. A matched group of nonsmokers served as a comparison group. Findings revealed that whereas adolescents who smoked a cigarette experienced reductions in both positive and negative affect, the observed reductions in negative affect were moderated by nicotine content of the cigarette (high yield vs. denicotinized), level of nicotine dependence, level of baseline craving, and smoking expectancies pertinent to negative affect regulation. Nonsmokers experienced no change in affect over the 10-min assessment period, and no interaction effects were observed for positive affect. Overall, the findings conform to a negative reinforcement model of nicotine effects and strongly suggest that, even among young light smokers, nicotine dependence and resultant withdrawal symptomatology may serve as motivating factors governing smoking behavior.

Coping styles and affect.

Most stress research has focused on testing the effects of coping strategies on negative outcomes such as distress, anxiety, and pathology. The present study focused on the effects of coping styles on the affective components of subjective well-being. Its main aim was to test differential associations between coping styles and positive and negative affect, using secondary analysis. The data were derived from 3 studies (n = 480) in which various samples—adolescents, university students, and a general population participants—completed trait version questionnaires of coping and affect. The main results, based on correlation and multiple regression analyses, showed that problem-focused coping was positively related to positive affect and negatively related to negative affect, whereas avoidance coping showed the opposite pattern of associations with positive and negative affect. Most important, problem-focused coping was found to be a moderator of avoidance coping effects on both positive and negative affective responses. The conclusions are that coping is an important factor in well-being during normal everyday life, and moreover, the interactive effects of coping styles merit further research.

A measure of positive and negative affect for children: Scale development and preliminary validation.

A child version of the Positive and Negative Affect Schedule (PANAS; D. Watson et al, see record 1988-31508-001), the PANAS-C, was developed using students in Grades 4–8 (N?=?707). Item selection was based on psychometric and theoretical grounds. The resulting Negative Affect (NA) and Positive Affect (PA) scales demonstrated good convergent and discriminant validity with existing self-report measures of childhood anxiety and depression; the PANAS-C performed much like its adult namesake. Overall, the PANAS-C, like the adult PANAS, is a brief, useful measure that can be used to differentiate anxiety from depression in youngsters. As such, this instrument addresses the shortcomings of existing measures of childhood anxiety and depression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age-related differences and change in positive and negative affect over 23 years.

Positive and negative affect, measured by the Bradburn Affect Balance Scale, were studied in a longitudinal sample spanning from 1971 to 1994. The sample (N?=?2,804) represented 4 generations of families. Linear trend analyses compared generations over time for positive and negative affect and also examined the possible influences of neuroticism and extraversion on initial levels of affect and patterns of change in affect. Negative affect decreased with age for all generations, although the rate was attenuated among the oldest adults. Higher neuroticism scores also attenuated the decrease in negative affect across time. For positive affect, the younger and middle-aged adults showed marked stability, but the older group evidenced a small decrease over time. Higher levels of extraversion were related to more stability in positive affect. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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)     

Genetic and environmental influences on positive and negative affect: Support for a two-factor theory.

Studied genetic and environmental etiologies of positive and negative affect, as measured by the Bradburn Affect Balance Scale, to gain understanding of a 2-factor theory of well-being. It was hypothesized that negative affect would demonstrate significant genetic and environmental variance and positive affect would be explained primarily by environmental influences. Data were combined from 105 pairs of twins (aged 18–72 yrs) and 220 multigenerational families (aged 16–98 yrs). Simultaneous model fitting indicated significant heritable effects for negative affect and a significant effect of common environment for twins. Significant effects for positive affect included common environment (for parents and offspring and for twin pairs) and assortative mating. These results, documenting differential genetic and environmental influences on positive and negative affect, provide further support for their being separate components of well-being.

The cost of good fortune: When positive life events produce negative health consequences.

Previous research regarding the effects of positive life events on physical health has been inconclusive. We tested the hypothesis that positive life events have a detrimental effect on health only among people with negative self-views. This prediction derives from an identity disruption model of stress, which holds that an accumulation of life events that are inconsistent with the self-concept leads to physical illness. To test the hypothesis, we conducted 2 prospective studies in which positive life events and self-esteem were used to predict the development of illness over time. In accordance with predictions, both studies showed that desirable life changes were associated with increases in illness only among Ss with low self-esteem; among Ss with high self-esteem, positive life events were linked to better health. Implications for understanding the manner in which life events affect health are considered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Transitions from negative affect during marital interaction: Husband and wife differences.

Negative-affect expression during marital interaction is the most consistent and powerful discriminator of marital quality. This negative-affect expression may also be influenced by gender. This investigation examined how covariates differentially influence, by gender, the "transitioning out" of negative affect during marital interaction. Self-report of negative affect was gathered in real time from 19 couples immediately after a positive interaction and a negative interaction. Event history analysis was used to determine covariate influence on the negative-affect hazard rate. Results indicated substantial gender differences. Wives were influenced by marital satisfaction, communication orientation, education, and previous durations of negative affect, whereas husbands were influenced only by education. For husbands, evidence was found suggesting that some covariate effects were moderated by time already spent in the negative state. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
