Between-Individual Differences in Baseline Well-Being and Emotion Regulation Strategy Use Moderate the Effect of a Self-Help Cognitive-Behavioral Intervention for Typical Adults.

BACKGROUND: Self-help interventions intended to help nonclinical individuals regulate their emotions can have important social benefits (i.e. mental disorder prevention, well-being promotion). However, their mean effect size on well-being is generally low, possibly because there are considerable between-individual differences in the response to these interventions. The present study examined whether individuals' baseline levels of emotional well-being and engagement in emotion regulation strategies moderate the effects on these same variables in a 4-week self-help cognitive-behavioral intervention intended for typical adults. METHODS: Data were collected from 158 nonclinical French adults (n = 95 for the control group, n = 63 for the cognitive-behavioral group) using experience sampling. Emotional well-being was assessed, as well as the engagement in three emotion regulation strategies (i.e. cognitive reappraisal, problem solving, and appreciation). RESULTS: As expected, the post-test scores on some variables were significantly predicted by the interactions between the intervention and the pre-test scores on these same variables. In particular, it was the participants with the most negative baseline levels (i.e. low emotional well-being, low engagement in appreciation) who benefitted most from the intervention. CONCLUSIONS: Results are discussed in the light of current knowledge on between-individual differences in how individuals respond to interventions.

Self-differentiation and eating disorders in early and middle adolescence: A cross-sectional path analysis.

This study examines the impact of self-differentiation, alexithymia and psychological distress on eating disorder symptoms in young and middle adolescence. Four hundred fifty-one adolescents completed self-report measures. Early and middle adolescents were categorized into two groups (12-14 years and 15-17 years) to represent distinct developmental stages. Significant differences were found between younger and older adolescents. The association between low self-differentiation and both eating disorders symptoms and psychological dimensions related to eating attitudes was stronger in early adolescence than in middle adolescence. The association between low self-differentiation and eating disorder symptoms was mediated by alexithymia and psychological distress in middle adolescence. Taken together, these findings suggest that self-differentiation could be useful in understanding psychological distress and alexithymia in eating disorders.

Characteristics of the spouse caregiving experience: Comparison between early- and late-onset dementia.

OBJECTIVES: To investigate the characteristics of the caregiving experience according to age at onset of dementia to adapt support programs. METHOD: Fifty-seven spouse caregivers of persons with early-onset dementia (PEOD) and 93 spouse caregivers of persons with late-onset dementia (PLOD) participated. The characteristics of the caregiving experience were assessed using questionnaires. We compared the two groups according to age at onset of the disease using a multivariate test, Pillai's Trace test. RESULTS: The analysis showed that there were similarities and differences between the two groups of spouse caregivers. All spouse caregivers were confident in their caregiving role and fairly well prepared for future needs and reported mild depressive and anxious symptoms. However, they lacked informal support, had low confidence in requesting respite care and reported effects on their health. Compared to spouse caregivers of PLOD, spouse caregivers of PEOD had more severe perceptions of the cognitive disorders of persons with dementia (PWD) and had a better sense of preparedness and knowledge of services. Spouse caregivers of PLOD were more confident in their ability to control disturbing thoughts. CONCLUSION: The results suggest that programs should provide information on support networks to improve preparedness for spouse caregivers of PLOD as well as emphasizing positive coping strategies for caregivers of PEOD to maintain good-quality relationships with PWD, which influences the perception of the symptoms. For both groups, family relationships should be considered.

Heart rate variability changes and emotion regulation abilities in short- and long-term abstinent alcoholic individuals.

INTRODUCTION: Difficulties in identifying and regulating emotion are recognized as major factors of relapse in alcohol use disorders (AUD). This study aimed to evaluate the differences of emotion regulation processes in AUD patients with short-term (STA, less than one month) and long-term abstinence (LTA, at least six months) by recording the high frequency of Heart Rate Variability (HF-HRV) in response to emotional and neutral stimuli. METHOD: Emotional induction constituted the presentation of highly emotional and neutral pictures (IAPS data base) presenting human interactions. HF-HRV was recorded before (at rest), during (pictures) and after emotional induction (recovery). RESULTS: The results showed higher phasic HF-HRV in the STA group in comparison to the LTA and C groups for negative, positive and neutral stimuli. In the LTA group, we observed a normalization of HRV, in response to emotional stimuli. However, for negative valence stimuli in the recovery period, LTA participants are no more different from STA group. A main positive correlation was observed for both patient groups between craving scores and increased HF-HRV during and after the emotion induction. CONCLUSION: The data support the hypothesis of emotion regulation impairment after STA but also show a partial improvement with prolonged abstinence. This impairment in patients may correspond to the maintenance of negative feedback that accentuates the difficulties in the emotional physiological process and limits the ability to engage in or maintain other processes. HF-HRV is a good indicator of emotion regulation processes related to the intensity of the craving even after long-term abstinence.

Modeling the Distress of Spousal Caregivers of People with Dementia.

BACKGROUND: The progressive mobilization of spouse caregivers who take care of a person with dementia (PWD) can lead to situations of distress. OBJECTIVE: The current study sought to investigate the influence of the characteristics of the caregiving context on spousal caregiver distress. METHODS: 125 spousal caregivers participated in this study. The characteristics of the caregiving context were assessed using questionnaires. We examined a moderated-mediator model (Step 1) in which we hypothesized that PWD and caregiver characteristics and dyadic determinants contribute to spousal caregiver distress. This model was compared based on the age at onset of the disease and the gender of the caregiver (Step 2). RESULTS: The model revealed that poor self-rated health and a lack of family support accentuated spousal caregiver distress, whereas the feeling of being prepared and level of confidence decreased spousal caregiver distress. Moreover, the quality of couple adjustment affected spousal caregiver distress, and this effect was mediated by the severity of the PWD's symptoms. Regarding the age at onset of the disease, the path between Couple Adjustment and the Care recipient's impairments was more important for caregivers of person with early-onset dementia (PEOD). Female caregivers who reported poor self-rated health experienced greater distress. CONCLUSIONS: It would be interesting to create a support program that would incorporate these three areas of intervention regarding the progression of the disease: first, "preparedness modules"; second, "dyadic modules" (especially for caregivers of PEOD); and third, "family modules". Specific attention should be given to female caregivers who report poor self-rated health.

Effects of emotion regulation difficulties on the tonic and phasic cardiac autonomic response.

BACKGROUND: Emotion regulation theory aims to explain the interactions between individuals and the environment. In this context, Emotion Regulation Difficulties (ERD) disrupt the physiological component of emotions through the autonomic nervous system and are involved in several psychopathological states. OBJECTIVE: We were interested in comparing the influence of a film-elicited emotion procedure on the autonomic nervous system activity of two groups with different levels of emotion regulation difficulties. METHODS: A total of 63 women (undergraduate students) ranging from 18 to 27 (20.7 ± 1.99) years old were included. Using the upper and lower quartile of a questionnaire assessing the daily difficulties in regulating emotions, two groups, one with low (LERD) and one with high (HERD) levels of emotion regulation difficulties, were constituted and studied during a film-elicited emotion procedure. Cardiac vagal activity (HF-HRV) was analyzed during three periods: baseline, film-elicited emotion, and recovery. RESULTS: The cardiovascular results showed a decrease in HF-HRV from baseline to elicitation for both groups. Then, from elicitation to recovery, HF-HRV increased for the LERD group, whereas a low HF-HRV level persisted for the HERD group. CONCLUSIONS: The HERD group exhibited inappropriate cardiac vagal recovery after a negative emotion elicitation had ended. Cardiac vagal tone took longer to return to its initial state in the HERD group than in the LERD group. Prolonged cardiac vagal suppression might constitute an early marker of emotion regulation difficulties leading to lower cardiac vagal tone.

Affiliative behaviour and conflictual communication during brief family therapy of patients with anorexia nervosa.

OBJECTIVE: Although patients with anorexia nervosa (AN) present positive responses to family therapy, the key features of therapeutic changes still require identification. This study explores the role of conflictual communication and affiliative nonverbal behaviour in therapeutic change in brief strategic family therapy (BSFT) for AN patients. METHODS: Ten female AN patients and their parents were included in the sample and took part in a 6-month follow-up of BSFT. The durations of conflictual communication and of affiliative nonverbal behaviour estimated by eye contact were compared between the first and the last sessions of family-based treatment using nonparametric statistical tests. RESULTS: An increase of the Body Mass Index associated with an increase in the conflictual communication expressed during BSFT sessions were observed. Moreover, affiliative nonverbal behaviour expressed by the father and the patient decrease, after a BSFT follow-up, in conflictual situations only. By contrast, no significant difference was observed in affiliative nonverbal behaviour expressed by the mother. CONCLUSION: The present study demonstrates that the impact of the BSFT differs between members of a family: the AN patient and the father have established a new form of emotional functioning with a decrease in emotional involvement. The study of the combination between verbal and nonverbal communication can represent an important step in the understanding of the mechanisms of therapeutic change.

Cognitive and physiological dissociations in response to emotional pictures in patients with anorexia.

Recent studies suggest that patients with anorexia may express dissociated cognitive and physiological reactivities to emotional stimuli. The present research aimed to compare subjective and autonomic responses to pleasant, unpleasant and neutral scenes during a categorization task and an activation rating task in anorexic (AN), alexithymic (AL), depressed (DEP) and control participants (CONT). The participants first categorized pictures according to their emotional valence, followed by a rating of their activation level, concomitant with the recording of skin conductance responses (SCRs). Main findings showed that the AN patients presented major difficulty in categorizing pictures, particularly neutral ones. Contrary to the AL participants, this difficulty did not induce significant increases of SCR amplitude in the AN patients. In the second task, the AN patients rated the intensity of activation of unpleasant pictures higher than the AL participants and that of pleasant ones higher than the AL and CONT participants. In addition, no significant linear correlation was observed between the intensity of activation ratings and SCR amplitude in the AN, AL or DEP participants contrarily to what was observed for control participants. This lack of relation suggests a non-specific disconnection between physiological and cognitive self-reported responses to emotional stimuli. Our results highlight a specific form of emotional processing in the AN patients distinct from that observed in alexithymia or depression and characterized by a dissociation between cognitive and physiological responses. This kind of disconnection could be associated with emotional regulation processes and may benefit the AN patients by lowering the psychological stress response.
