Manipulation of self-esteem as a determinant of mood of elated and depressed women.

Tested the theory that self-esteem is a determinant of elation-depression. Changes in self-esteem were induced by having Ss read positive or negative self-evaluative statements. 140 female college students were selected on the basis of extreme scores of characteristic elation and depression and on the basis of suggestibility and were assigned to 1 of 5 treatment or control groups. The induction of positive vs negative cognitions produced significant differences in elation-depression on multiple measures. Characteristically elated and depressed Ss were able to take on opposite mood states. This study suggests that a determinant of depression is evaluative self-statements, supports the utility of cognitive therapy for depressives, and demonstrates a potentially useful technique for inducing more appropriate self-evaluations.

Manipulation of thought content as a determinant of mood and corrugator electromyographic activity in depressed patients.

In 5 single-S experiments, depressed mood and corrugator EMG were measured while 5 female depressed psychiatric hospital day-clinic patients thought happy and unhappy thoughts. Results show that mood was significantly more depressed after unhappy thoughts for all Ss. During the 2nd half of the thought periods, corrugator EMG was higher in the unhappy condition than in the happy condition for all Ss, significantly so for all but one. Significant positive correlations between depressed mood and corrugator EMG were obtained in all Ss. Findings are discussed in relation to cognitive theories of depression and to the usefulness of corrugator EMG as an index of depressed mood.

Reversal of cognitive and affective deficits associated with depression and learned helplessness by mood elevation in patients

Therapeutic implications of the learned helplessness model of depression were tested in a clinical population (48 male medical and psychiatric patients of a VA hospital). In pretreatment, 2 groups of nondepressed medical patients waited, 2 groups of nondepressed medical patients received helplessness training, and 2 groups of psychiatric patients (diagnosed as primary affective disorder) waited. In treatment, Ss received either E. Velten's (1968) mood-elation procedure as "therapy" or Velten's (1968) mood-neutral procedure as placebo. Performance on cognitive and mood tasks was assessed. Three separate administrations of the Depression Adjective Check List indicated that helplessness training induced depressive affect, and the mood elation procedure decreased depressive affect for both helpless and depressed Ss. The mood neutral procedure and the waiting periods were associated with no affective changes. On the cognitive (anagrams) task, performance deficits were associated with helplessness and depression but were reversed by mood elation. Results are interpreted as consistent with the learned helplessness model of depression. (23 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An attempt to reverse performance deficits associated with depression and experimentally induced helplessness.

The learned helplessness model of depression predicts that any effective treatment for reactive depression should also reverse performance deficits associated with experimentally induced helplessness, and vice versa. A study was conducted to test this prediction. Ss were 62 college students who were exposed to experimental manipulations designed to induce helplessness or who scored above a group mean on the Beck Depression Inventory. Depressed and helpless Ss were randomly assigned to 4 groups. The 2 treatment groups received either E. Velten's (1968) mood statements for the induction of elation or a set of simple anagrams to solve. The 2 remaining groups were exposed to no-treatment conditions. All Ss were tested for helplessness on a series of concept formation problems. Results fail to confirm the predictions of the learned helplessness model of depression. Although treatment was effective with helpless Ss, the performance of treated depressed Ss was not enhanced. Also, depressed Ss given anagrams performed more poorly than depressed Ss given mood statements. Several possible explanations for the findings are considered.

Effects of induced elation-depression on speech in the initial interview.

Examined the relationship between induced mood states of elation or depression and interviewee verbal behavior. Affective states were manipulated through the use of an autosuggestion technique (mood induction procedure; MIP). Ss were 45 female college students, ages 17-23, assigned to 1 of 3 treatment conditions: elation, depression, or neutral mood induction. Data consisted of 15 telephone dialogues elicited by an automated initial interview in each of the 3 mood conditions, with the MIP occurring midway in the interview. Criterion measures indicated that the MIP did successfully produce authentic emotional responses in the interviewee; postinterview questioning revealed that the interviewees did not discern the automated nature of the interviewer. Elation was found to evoke shorter response latencies, faster speech and articulation rates, and fewer silent pauses (2 sec or longer) than in a control group. Depression was positively related to silent pauses. Findings are discussed in terms of previous psycholinguistic research on the "cognitive" role of speech timing.

Facial expression and imagery in depression: an electromyographic study

When subjects are instructed to self-generate happy, sad, and angry imagery, discrete patterns of facial muscle activity can be detected using electromyographic (EMG) procedures. Prior research from this laboratory suggests that depressed subjects show attenuated facial EMG patterns during imagery conditions, particularly during happy imagery. In the present experiment, 12 depressed subjects and 12 matched normals were requested to generate happy and sad imagery, first with the instruction to simply "think" about the imagery, and then to self-regulate the affective state by "reexperiencing the feelings" associated with the imagery. Continuous recordings of facial EMG were obtained from the corrugator, zygomatic major, depressor anguli oris, and mentalis muscle regions. It was hypothesized that (a) these muscle sites would reliably differentiate between happy and sad imagery. (b) the instruction to self-generate the affective feeling state would produce greater EMG differences than the "think" instructions, and (c) the "think" instructions would be a more sensitive indicator of the difference between depressed and nondepressed subjects, especially for happy imagery. All three hypotheses were confirmed. The application of facial electromyography to the assessment of normal and clinical mood states, and the role of facial muscle patterning in the subjective experience of emotion, are discussed.     

An investigation of cognition and affect in the depressive experiences of normal men.

Administered the Depression Adjective Check List and a projective story completion test as measures of depression to 30 male undergraduates 5 times over a 2-mo period. Data demonstrate the existence of a unified, negative content that is associated with depressed mood among normal Ss and suggest a similarity in the depressive processes of pathological depression and depressed mood.

Construct accessibility and depression: An examination of cognitive and affective factors.

Two experiments with undergraduates examined the parameters of construct accessibility in depression. In Exp I, 30 depressed and nondepressed (the Beck Depression Inventory) Ss were required to name the colors of tachistiscopically presented depressed-content, neutral-content, and manic-content words. Because of the predicted accessibility and interference effects of the depressed-content words, depressed Ss were predicted to demonstrate longer response latencies to these words than to the non-depressed-content words. Results support the prediction: Nondepressed Ss did not demonstrate differential response latencies. In Exp II (30 Ss), a mood-induction paradigm was used to investigate whether the interference effects obtained in Exp I were due to temporary mood differences between depressed and nondepressed Ss or were a function of more stable depression-associated patterns of information processing. Although predicted group differences were obtained on a mood adjective checklist, no effects were found for task performance. Findings suggest that transient mood is not a sufficient explanation for the results obtained in Exp I. Implications for the understanding of both construct accessibility and depression are discussed. (68 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-devaluation and depressed mood.

E. Velten's (1968) mood induction procedure (VMIP) has been used in a variety of studies to induce depressed moods. Its effectiveness has been attributed to the self-devaluative nature of its statements, and it has been used as support for cognitive self-evaluation theories of depression. An alternative hypothesis is that suggestions of somatic states characteristic of depression, which are found in nearly half of the VMIP depression statements, account for the effectiveness of the procedure. 60 female college students were randomly assigned to 5 groups: VMIP depression, VMIP elation, VMIP neutral, somatic suggestion, and self-devaluation. The VMIP depression statements were divided into those that suggest somatic states characteristic of depression, (e.g., fatigue and exhaustion) and those that are self-devaluative, (e.g., statements of low self-worth) to form the somatic suggestion and self-devaluation conditions. Somatic suggestion Ss reported more depressed mood than neutral Ss. Somatic suggestion Ss also reported more depressed mood than self-devaluation Ss on several measures. Results support a somatic suggestion hypothesis and offer no support for self-devaluative interpretations of VMIP effects. This limits the support VMIP studies offer to cognitive self-evaluation theories of depression. (15 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Emotional responding following experimental manipulation of facial electromyographic activity.

Thirty female subjects were instructed to imagine three positive affective scenes and three negative affective scenes. During the initial imagination of each scene, the subject was told simply to imagine the situation. The subject then imagined the situation again and was instructed to enhance the muscle tension in one of two muscle groups (the zygomatic muscles for positive scenes and the corrugator muscle for negative scenes). The subject then imagined the scene a third time and was instructed to suppress the muscle tension in the same muscle group. Feedback was available during practice trials and during the enhancement and suppression trials of the experiment. Continuous monitoring of both zygomatic and corrugator electromyogram (EMG) during the study indicated that subjects were successful in altering muscle tension in accord with the experimental instructions, and videotapes of subjects' faces indicated no overt changes in facial responding during imagination of the scenes. Subjects' ratings of emotional responding during each scene indicated that subjects experienced less enjoyment and more distress during positive affective trials in which they suppressed zygomatic EMG activity. The results are discussed in terms of the facial feedback hypothesis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of self-induced mood states on behavior and physiological arousal

The effects of reading emotionally loaded statements on behavioral tasks and physiological measures were investigated. Statements were constructed to arouse elation, depression, or neutrality. Ss were both pre- and posttested on Writing Speed, Reaction Time, Decision Time, and Spontaneous Verbalizations. Base rates were obtained for heart rate and galvanic skin response. Elation Ss significantly outperformed both Neutral and Depression Ss on the Reaction Time task. Scores for Neutral Ss fell between those of Elation and Depression Ss on three of the four behavioral measures. No significant differneces were found on the physiological measures.     

Premenstrual and menstrual mood changes in adolescent women.

Studied the presence and magnitude of menstrual-cycle-related mood changes using standardized measures of depression and anxiety. 158 females aged 15–16 yrs completed the Menstrual Distress Questionnaire and reported the actual date of onset of their next 2 menstrual periods. These Ss and their male classmates were later given the Depression Adjective Check List, Forms A and D, and the State-Trait Anxiety Inventory twice, 2 wks apart, in an unrelated classroom setting. This study assessed the magnitude of anxiety and depression experienced by the 29 Ss who were tested within 4 days preceding the onset of menstruation and the 23 Ss who were tested during the first 4 days of menstruation. Premenstrual and menstrual test scores were compared with those obtained during the intermenstrual phase of the cycle. No significant differences in mood attributable to cycle phase were found. A control group of males also showed no significant difference in mood. Adolescent women appear to be different from women over 30 who have been reported to show significantly increased state anxiety and depression during the premenstrual phase of the menstrual cycle.

Expectancies, mood, and performance of depressed and nondepressed psychiatric inpatients on chance and skill tasks.

The learned helplessness model of depression predicts that, compared with nondepressed patients, depressed patients will demonstrate psychomotor deficits, provide lower subjective evaluations of their performance, and perceive reinforcement in skill tasks as more response independent. These predictions were tested in 32 depressed (mean age 35 yrs) and 32 nondepressed (mean age 38 yrs) psychiatric inpatients, who had been administered the Quick Test and the Beck Depression Inventory. Ss performed card- and peg-sorting tasks in which measures of performance, ratings of mood and expectancy of success, and subjective evaluations of performance were obtained under chance and skill reinforcement conditions. Although some support was obtained for the prediction that depressives provide lower evaluations of their performance than nondepressives, the other predictions were not supported. Comparisons between depressed and nondepressed schizophrenics indicate that the mood of depressed schizophrenics was especially sensitive to task outcome for both skill and chance conditions.

Synergistic effect of iontophoresis and a series of fatty acids on LHRH permeability through porcine skin

This study examined physiological response to an encounter with and touch by an unfamiliar person. Fifty-five African American (23 male, 30 female) and 51 European American (23 male, 28 female) undergraduates participated. A Black or White interactor entered the room, introduced himself or herself, checked equipment for 30 s, and then took a pulse for 30 s. Entry of the interactor resulted in increased corrugator and zygomaticus facial muscle activity (EMG), increased skin conductance (SC), and heart rate (HR) acceleration. Corrugator EMG was greater among Black subjects; White subjects responded with more zygomatic EMG and SC and greater HR acceleration. Women showed a more positive facial expression than did men. Being touched reduced EMG and HR but resulted in increased SC. White and Black males showed more HR acceleration when encountering a Black male interactor.     

Cognitive influences on the development of learned helplessness.

120 college students participated in an experiment concerning the influence of self-statements following failure on subsequent symptoms of learned helplessness (LH). 40 Ss were given solvable concept-formation problems (nonhelpless condition), and 80 Ss were given unsolvable problems (helpless condition). MANOVA revealed a significant difference between helpless and nonhelpless Ss on cognitive/motivational and affective measures of LH and on self-statements regarding performance. However, when multiple regression and correlational analyses were performed within the group of Ss who failed the problems, no stable relationship was found between self-statements (cognitions) about concept-formation performance and the LH measures. Implications for A. T. Beck's (1967) cognitive model of depression and the reformulated LH model of depression (L. Y. Abramson et al, 1978) are discussed.

Self-schemas and risk for depression: A prospective study.

Two longitudinal experiments with 375 undergraduates investigated the role of depressive self-schemas in vulnerability to depression. Ss were divided into 5 groups hypothesized to be at differential risk for depression according to a schema model: depressed schematic, depressed nonschematic, nondepressed schematic, nondepressed nonschematic, and psychopathology control. In Exp I, Ss were followed regularly for 4 mo with self-report and clinical interview measures of depression (e.g., Beck Depression Inventory). There was no evidence of risk for depression associated with schema status apart from initial mood and no interaction of life stress events and schemas. In Exp II, links among self-schemas, information processing, and mood status were investigated. It was shown that depressive self-schemas did not exert an ongoing, active influence on everyday information processing; instead, current mood affected information processing. Remitted depressed Ss resembled nondepressed rather than depressed Ss. Findings support the distinction between concomitant and vulnerability schemas noted by N. Kuiper et al (in press) and help to clarify differences between cognitions that are symptoms of depression and those that may play a causal role under certain conditions.

In defense of the Velten mood induction procedure.

Examined whether the Velton Mood Induction procedure (VMIC) (E. Velton, 1968) produced mood effects only through demand characteristics, in 2 studies. In study 1, 50 undergraduates were assigned to 1 of the 5 mood conditions: Positive, negative, neutral, and positive and negative demand. They were presented the VMIC, and were then asked to complete the Multiple Affect Adjective Check List (MAACL). In study 2, 49 Ss were assigned to 1 of 4 imagine conditions with target moods: Elated, depressed, in a positive or negative mood; and were then asked to complete the MAACL. Mood effects of the VMIC were genuine and not simply the product of demand characteristics. Ss reported mood change after reading the VMIC. The VMIC did not provide Ss with information about a mood state that they did not already know, and Ss did not respond more extremely to the moods of depression and elation as compared to negative and positive moods.

Effect of depressed mood on eating among obese and nonobese dieting and nondieting persons.

Induced a depressed or nondepressed mood in obese and nonobese dieters and nondieters (18 male and 38 female undergraduates). Ss were administered a battery of measures, including the Beck Depression Inventory and Depression Adjective Check List. As predicted, dieters ate more when depressed than when nondepressed, and nondieters ate less when depressed than when nondepressed. That is, both groups reversed their typical eating patterns when depressed. Also as predicted, among depressed Ss, dieters ate more than nondieters; among nondepressed Ss dieters ate less that nondieters. This pattern of results was found for both obese and nonobese Ss. Dieting habits were highlighted as a more salient variable than obesity in predicting eating responses to depressed mood. Findings are discussed with respect to the psychosomatic theory of obesity, the stimulus-binding theory of obesity, previous investigations of clinical depression, and the theory of restrained eating.

Some relations between pleasant and unpleasant mood-related events and depression.

Studied (a) the validity of 2 methods of identifying reinforcing and punishing events, (b) their interrelations and dimensional structure, and (c) their relation to depression. A total of 909 Ss who were screened with the MMPI and classified as depressed, nondepressed psychiatric, or normal control rated the frequency and the subjective enjoyability or aversiveness of 320 pleasant (the Pleasant Event Schedule Form III) and 320 unpleasant events (the Unpleasant Events Schedule Form I). Some Ss also monitored the occurrence of pleasant and unpleasant events and rated their mood on a daily basis (Depression Adjective Check List). Correlations between each event and mood were calculated and used to identify 49 pleasant and 35 unpleasant "mood-related events." The proportion of Ss for whom the events correlated with mood and the mean enjoyability and aversiveness of the items were hypothesized to be measures of reinforcing or punishing impact. As predicted, statistically significant correlations between these 2 measures were obtained. The mood-related events also discriminated more strongly between depressed and nondepressed groups than the non-mood-related events did. The intercorrelations between pleasant and unpleasant events yielded separate and orthogonal dimensions of punishment and of reinforcement.

Vulnerable self-esteem and depressive symptoms: Prospective findings comparing three alternative conceptualizations.

Across diverse theoretical orientations, vulnerable self-esteem (SE) is thought to act as a diathesis for depression after life stress. In the present study, the roles of trait-level SE, low SE primed by depressed mood, and labile SE in prospectively predicting changes in depressive symptoms in a nonclinical sample (n?=?192) were examined. Results indicate that labile SE predicted increases in symptoms. Furthermore, a 3-way interaction (Labile SE?×?Academic Stress?×?Initial Depression) suggested that in Ss who were initially asymptomatic, lability made Ss differentially vulnerable to increases in depressive symptoms after stress. In contrast to labile SE, trait-level SE and priming of low SE were relatively weak predictors of changes in depressive symptoms and did not interact with stress.
