The effect of depressed mood on the interpretation of ambiguity,with and without negative mood induction

Is there an effect of depressed mood on the interpretation of ambiguity? Are depressed individuals biased to interpret ambiguous information in a negative manner? We used a cross-modal semantic priming task to look for evidence of a negative interpretative bias. Participants listened to ambiguous prime sentences (e.g., Joan was stunned by her final exam mark) and made lexical decisions to target words presented immediately after the sentence offset or after a delay of 1000 ms or 2000 ms. For the semantically related targets, the target was negatively related (distress), positively related (success), or neutrally related (grades) to the ambiguous prime. The experiment was conducted with and without a negative mood induction. The expectation was that depressed participants would be more likely to consider the negative interpretations of the ambiguous primes and would therefore experience larger priming effects for negatively related targets. Although there were large priming effects for all semantically related targets, there was no evidence of a negative interpretative bias.     

Interpersonal mood induction: Situational and individual determinants

Several situational and individual aspects of interpersonal mood induction were investigated in an attempt to elucidate the mechanisms by which depressed mood is transmitted from one individual to another. Eighty-four psychology students interacted with confederates previously trained to enact one of three mood states — depressed, neutral, or elated. Participants were randomly assigned to same-sex confederates in one of two roles — helper or stranger, resulting in a 3×2×2 design. Mood and self-esteem were independent variables assessed prior to the interaction. Mood, perceptions, and reactions to the confederate were dependent variables assessed following the interaction. Results indicated induction of depression and anxiety in participants exposed to depressed confederates, and induction of hostility following interaction with elated confederates. Induction of depression and hostility were significantly attenuated in participants in the helper role as opposed to person perception role, while the concept of individual vulnerability to mood induction was not supported in this study. Rejection of depressed persons was only modestly associated with negative mood induction. Thus, role components of the situation affected mood induction more than did individual participant differences. The results and their implications for therapists and family members of depressed individuals are discussed within the framework of Lazarus's cognitive model of emotional arousal.The authors gratefully acknowledge the contributions and talents of Bill Dorfman, Mike Harrington, Ginger Johnson, Anita Navarra, and Debbie Illman.     

Relative effectiveness and validity of mood induction procedures: a meta-analysis

The effectiveness and validity of 11 important mood induction procedures (MIPs) were comparatively evaluated by meta-analytical procedures. Two hundred and fifty effects of the experimental induction of positive, elated and negative, depressed mood in adult, non-clinical samples were integrated. Effect sizes were generally larger for negative than for positive mood inductions. The presentation of a film or story turned out to be most effective in inducing both positive and negative mood states. The effects are especially large when subjects are explicitly instructed to enter the specified mood state. For elated mood, all other MIPs yielded considerably lower effectiveness scores. For the induction of negative mood states, Imagination, Velten, Music, Social Interaction and Feedback MIPs were about as effective as the Film/Story MIP without instruction. Induction effects covaried with several study characteristics. Effects tend to be smaller when demand characteristics are controlled or subjects are not informed about the purpose of the experiment. For behavioural measures, effects are smaller than for self-reports but still larger than zero. Hence, the effects of MIPs can be partly, but not fully due to demand effects.     

Instructions and group versus individual reinforcement in modifying disruptive group behavior

Head Start children were matched into two groups on the basis of rates of disruptive behavior during rest periods. Attempts were made to modify their behavior using either individual or group token reinforcement procedures. While the reinforcement procedures reduced inappropriate behavior somewhat, the addition of instructions to the reinforcement reduced the inappropriate behavior to near zero for both groups. Instructions alone, however, were ineffective in controlling behavior. Type of reinforcement (group or individual) did not produce differential effects. While experimental control over the target behavior was demonstrated, there was little carryover from the experimental room to the regular classroom. Even when treatment was introduced into the regular class, follow-up results showed that with time the target behavior approximated pretreatment levels. The results suggest that (a) the combination of instructions and reinforcement is much more effective than either one of these alone, (b) behavior change is specific to the environmental contingencies, and (c) the group reinforcement technique, which is much more easily implemented, was at least as effective as individual reinforcement in the present study.     

The effects of gender and response style on depressed mood

Research has shown that gender differences in the rate of depression may be accounted for by different response styles. To examine whether response style affects mood, depressed mood was induced in 31 females and 33 males (all Caucasian) who were then randomly assigned to either a ruminating or a distracting response task. The findings supported the response style theory as the ruminating group remained depressed after the response task, while the distracting group became less depressed. Gender was not a factor in this experiment as both men and women reacted similarly to the mood induction and the experimental tasks. Although clinical implication cannot be determined from a study involving nondepressed subjects, it can be concluded that ruminating about one's depressed mood is not an effective method for overcoming depression.     

Concurrent group and individual psychotherapy in a psychiatric day hospital for depressed elderly

Concurrent psychotherapy is used in various settings for patients of different diagnoses and ages. The concurrent group and individual psychotherapy of older adults with depressive disorders in a psychiatric day hospital is described, emphasizing phases of treatment and transference and countertransference themes uniquely relevant to working with depressed elderly patients in a day hospital. Case examples are offered to illustrate these issues. The special technical considerations that need to be utilized when multiple therapists and settings are present are described. The model employs the use of an integrative, interactive group therapy, along with various other group treatments and antidepressant medication, with individual therapy serving a subordinate but organizing role.     

Correlates of depressed mood in normal children

Two instruments which have been proposed as measures of clinical depression in children and an ad hoc teacher rating were given to a group of 109 normal children. The Children's Depression Inventory (CDI), the Peer Nomination Inventory for Depression (PNID), and a teacher rating of depression were given along with the Conner s Teacher Rating Scale (TRS), teacher ratings of somatic complaints, peer popularity, and absenteeism, and peer ratings of popularity to examine the behavioral correlates of depressed mood in normal children. While few sex differences were found on mean depression scores, different patterns of correlations were found for the two sexes. For males, there were no significant correlations among the three depression measures, but all three depression measures were correlated with unpopularity and conduct problem ratings on the TRS. For females, the three depression measures were adequately intercorrelated. The teacher rating of depression was correlated with general deviance as measured by the TRS, but the CDI and PNID were correlated with TRS ratings of conduct problems, with peer ratings of unpopularity, and with teacher ratings of somatic complaints. Implications for the issue of the possible existence of a clinical syndrome of depression in children were discussed.     

A study of diurnal patterns of depressed mood

The study investigated diurnal patterns of depressed mood in a sample of normal subjects. In all, 105 college undergraduates were followed for a period of 10 days, using a self-administered psychological diary. Eighty-four percent of the days in which feelings of depressed mood were reported involved some type of mood swing. The most frequent pattern of mood shift was a pattern of gradually increasing depressed mood, reaching its peak in the evening. Persons who reported days of constant depressed mood reported higher levels of physical symptoms and less pleasure in social interactions than persons who reported only depressed days involving mood swing.     

Cognitive therapy for social phobia: individual versus group treatment

Cognitive-behavioural group treatment is the treatment of choice for social phobia. However, as not all patients benefit, an additional empirically validated psychological treatment would be of value. In addition, few studies have examined whether a group treatment format is more effective than an individual treatment format. A randomized controlled trial addressed these issues by comparing individual cognitive therapy, along the lines advocated by Clark and Wells (Clark, D.M. and Wells, A., 1995. A cognitive model of social phobia. In: R. G. Heimberg, M. Liebowitz, D. Hope and F. Schneier (Eds.), Social Phobia: Diagnosis, assessment, and treatment (pp. 69-93). New York: Guilford.), with a group version of the treatment and a wait-list control condition. 71 patients meeting DSM-IV criteria for social phobia participated in the trial, 65 completed the posttreatment assessment and 59 completed a six-month follow-up. Social phobia measures indicated significant pretreatment to posttreatment improvement in both individual and group cognitive therapy. Individual cognitive therapy was superior to group cognitive therapy on several measures at both posttreatment and follow-up. The effects of treatment on general measures of mood and psychopathology were less substantial than the effects on social phobia. The results suggest that individual cognitive therapy is a specific treatment for social phobia and that it's effectiveness may be diminished by delivery in a group format.     

Interactions between emotion regulation strategies and affective style: Implications for trait anxiety versus depressed mood

Affective style reflecting approach and inhibition is thought to be associated in distinct ways with anxious versus depressed mood; relatively few studies, however, consider how the interaction between affective style and the strategies individuals use to regulate mood and emotion might influence these associations. Sixty-seven non-disordered adults self-reported on their use of two emotion regulation strategies (cognitive reappraisal and expressive suppression), behavioral approach (BAS) and behavioral inhibition sensitivity (BIS) dimensions of affective style, and anxious and depressed mood (trait anxiety and symptoms of depression). Trait anxiety versus depressed mood was associated with unique interactive patterns of emotion regulation and affective style: enhanced use of reappraisal was linked to less depressed mood in those reporting low BAS, whereas high suppression was linked to greater trait anxiety in those reporting low BIS. The implications of findings for typical emotional processes and for clinical disorders and interventions are discussed.     

Maternal depressed mood and perceptions of child temperament

Research has suggested that women who experience postpartum depression are subsequently more likely to perceive their preschool-aged children as temperamentally difficult and maladjusted. However, previous studies have not controlled for the effects of concurrent depression levels on maternal ratings of child temperament or evaluated the accuracy of maternal reports. In the present study we assessed maternal and paternal ratings of child temperament 2 years after subjects had participated in a study of postpartum depression. The findings indicate that correlations between postpartum depression and subsequent child temperament ratings were accounted for statistically by concurrent levels of depression. Although fathers' ratings corroborated some aspects of maternal perceptions, levels of parental agreement were only moderately high. Moreover, discrepancies between the parents' reports were significantly associated with maternal depression, indicating that parental disagreement is more likely when the wife is dysphoric.     

Assessing the effectiveness of drawing an autobiographical memory as a mood induction procedure in children

The objective of our study was to examine the effectiveness of a new version of the autobiographical recall procedure (i.e., drawing a happy personal event) in eliciting a positive mood in 6-, 8-, and 10-year-old children and to compare the drawing condition to the more classical telling condition. The mood of children was assessed before and after induction using the Self-Assessment Manikin (SAM) and across the two emotional dimensions of valence and arousal. The results showed that the drawing condition was as effective as the telling condition for inducing a positive mood. Furthermore, in the drawing condition, children reported feeling calmer than in the telling condition, suggesting that drawing was more likely to help children regulate their emotional state. The drawing procedure could be used in future research aiming to induce positive moods in school-aged children, to help further investigate the relationship between cognition and emotion.     

A meta-analysis of estimated effect sizes for group versus individual control treatments

A meta-analysis was conducted combining results from nine studies, using seventy-five outcome measures of 349 subjects. Only studies that contrasted group, individual, and control treatments with a pretest-posttest design were selected. Estimates of effect sizes were calculated for group, individual, and control treatments across all studies, according to treatment modality (psychotherapy, counseling, or psychoeducation), type of control (no treatment or some treatment), date of the study (1955-1969 or 1977-1982), and the subjects' age (adult, adolescent, or child). Results indicated that both group and individual treatments had a measurable effect that was consistently greater than that of controls. Further, (1) counseling produced much more of an effect than either therapy or psychoeducation; (2) the more recent treatments produced larger effects than the older studies; and (3) group treatments were more effective than individual methods in the treatment of adolescents, but were less effective in the treatment of children.     

Group versus individual reinforcement contingencies within the context of group study conditions

We investigated the effects of two teaching variables on students' Spanish vocabulary quiz performance: (a) group study and (b) individual versus group contingencies. In Experiment 1, we compared students' quiz scores under conditions in which students either studied independently and received no programmed reinforcement or studied in groups and received individual rewards for high scores. The results showed that, on average, the group-study individual-reward condition produced superior quiz scores. In Experiment 2, we compared individual (i.e., the superior condition in Experiment 1) and group contingencies within the context of the group study condition. On average across the class, group contingencies produced performance superior to individual contingencies. In both studies, however, benefits for the classes as a whole were mitigated by effects on individual students. These results extend the literature on the effects of group-based instructional activities and reinforcement contingencies. Educators who choose such procedures may encounter conflicting findings depending on whether they examine results at the group or individual level.
