Self-regulatory control processes in youths: A temporal network analysis approach

Objective

This study aimed to better understand the temporal interrelationships among self-control, response inhibition, and anger (i.e., momentary state and rumination) on both the within- and between-person levels in male adolescents.

Method

We applied temporal network analyses among 62 male adolescents with a wide range of behavioral difficulties. Self-control, momentary anger, and anger rumination were mapped by self-report measures, whereas we measured response inhibition through an ambulatory Go/No-go task (two measures a day-morning and afternoon-over a 9-day period).

Results

Temporal network analysis, at the within-person level, revealed that morning measures of response inhibition, anger rumination, and self-control were related to the corresponding measure in the afternoon. More efficient response inhibition in the morning was associated with higher self-control in the afternoon. Higher anger rumination in the morning led to higher momentary anger in the afternoon. In a concurrent within-person network, higher momentary anger was reciprocally associated with lower self-control. At the between-person level, higher momentary anger was correlated to higher anger rumination, lower response inhibition, and lower self-control.

Discussion

This study provides insight into the dynamic interactions among self-control, response inhibition, and anger (momentary state and rumination) in male adolescents, advancing the understanding of self-regulatory control functioning.

[Profile of the victims of sexual violence in child psychiatry consultation]

INTRODUCTION

Child sexual abuse is a major health problem that remains under-declared and under-reported worldwide. In this paper we have taken an interest in establishing the profile of the victims in a clinical population of children consulting for sexual abuse.

METHOD

We conducted a descriptive retrospective study in the child and teenager psychiatry department of the Mongi-Slim hospital (Tunis, Tunisia). We included all patients referred for treatment or medical expertise during the period from January 2013 to June 2019 and recorded sociodemographic data and clinical characteristics on pre-established charts from patient files.

RESULTS

The total number of consultants was 150 patients with 61,33 % of female subjects (n=92). The average age was 9,9 years old with extremes ranging from 2 to 18 years old. The assault was unique in 62,7 % and happened in a place known by the victim in 47,33 %. Sexual abuse with non-penetrating contact was the most frequent (48 %). The average age at which the first sexual abuse happened was 9 years old. In the vast majority of cases, the abuser was a male. Concerning the identity of the abuser, he was someone of the family in 37,3 % of the cases and in half of these cases, he was the father. In the other cases where the abuser wasn't a family member, the identity was known by the child and/or his family in 48,66 %. A psychiatric diagnosis was made in 58 % of the cases with a percentage of 52,1 % among girls and 60,3 % among boys. Main diagnoses were acute stress disorder in 10,6 %, post trauma stress disorder in 19,3 %, adjustment disorder in14,6 % and a major depressive disorder in 8 %.

CONCLUSION

Knowing the profile of victims of child sexual abuse and taking into consideration the social and psychiatric impact can help in adapting the means to intervene properly in order to take care of the victims and prevent such abuse.

Identifying the determinants of perceived quality in outpatient child and adolescent mental health services from the perspectives of parents and patients

This cross-sectional survey adopting a multiple-informant perspective explores the factors that influence perceived quality (i.e., therapeutic alliance and satisfaction) in an outpatient setting within child and adolescent mental health services (CAMHS). A total of 1433 participants (parents, n = 770, and patients, n = 663) attending or having attended (drop-out) outpatient units participated in the study. The outcome measures were satisfaction (Client Satisfaction Questionnaire) and the therapeutic alliance (Helping Alliance Questionnaire). The determinants of these quality indicators were socio-demographic variables (e.g., age, gender, and mother's socio-economic status), factors related to the extent of difficulties (number of reasons for the consultation, number of people who referred the child to the CAMHS), the approach to treatment at outset (agreeing to the consultation, feeling reassured at the first appointment), the organizational friendliness (secretary, waiting room, waiting time for the first appointment) and the organization of the therapy (frequency of sessions, time for questions, change of therapist). The approach to treatment at outset, accessibility by phone, satisfaction with the frequency of the sessions and having enough time for questions were the factors that consistently explain the quality indicators from both perspectives (patients and parents). In contrast, the socio-demographic variables as well as the extent of difficulties and factors related to the organizational friendliness and the organization of the therapy (frequency of sessions, change of therapist) were not related to the quality indicators. This study identifies key determinants of the quality indicators from the perspective of patients and parents that should be considered to improve CAMHS care quality. First appointments should be carefully prepared, and clinicians should centre care on the needs and expectations of patients and parents.

[Towards a partnership-based care approach to adolescence]

The transition from child psychiatry to adult psychiatry is difficult. The need to reinforce this 'bridge' between the services is clear. A system focused on the assessment and orientation of adolescents, set up a year ago by Lille-Métropole public mental health service, aims to favour collaboration on a local level between the different players from the social, medical and educational sector working with young people aged between 12 and 21 in order to facilitate this transition.

Psychometric properties of a pictorial instrument for assessing psychopathology in youth aged 12 to 15 years: the Dominic Interactive for Adolescents

OBJECTIVES

Over the last 15 years, adequate psychometric properties of the different versions of the Dominic led to the development of the Dominic Interactive for Adolescents (DIA). The DIA is a Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition, Text Revision-based self-administered computerized pictorial instrument for assessing the most frequent mental disorders in adolescents aged 12 to 15 years. Our study aims to verify the internal consistency, the test-retest estimate of reliability, and the criterion-related validity of this instrument.

METHOD

The total sample included 607 adolescents living in the Montreal urban area recruited from the community (465 French-speaking) and the clinical population (142 French-speaking). Internal consistency was evaluated by Cronbach's alpha coefficients and test-retest estimate of reliability by the kappas and intraclass correlation coefficients (ICCs). Two criteria are indicative of criterion-related validity of the DIA: clinical judgment on the presence or absence of symptoms (scored independently by 3 judges) and the adolescents' referrals to outpatient psychiatric clinics.

RESULTS

For most symptom scales of the DIA, Cronbach's alpha coefficients varied from 0.69 to 0.89, test-retest kappas were 0.50 or greater, and ICCs ranged from 0.78 to 0.87. The criterion-related validity was demonstrated for symptoms, symptom scales, and the categories based on the symptom scale cut-off points.

CONCLUSION

As no informant can be considered the criterion standard of psychopathology, the interview with adolescents regarding their own symptoms is necessary. Findings from our study reasonably support adequate psychometric properties of the DIA in adolescents aged 12 to 15 years.

Prevalence and patterns of methylphenidate use in French children and adolescents

OBJECTIVE

The aim of the study was to describe the prevalence and utilization patterns of methylphenidate (MPH) in children and adolescents in France.

METHODS

This was a population-based retrospective study in which the cohort consisted of patients for whom data were extracted from the dispensation drug claims database of the national health insurance (NHI) fund for self-employed workers. Annual prevalence of MPH use was evaluated on patients aged 6-18 years who were reimbursed for at least one MPH prescription a year. Between January 2004 and June 2005, features of MPH medication and user profile were described for the "new starters" having a screening period of 1 year without receiving a MPH prescription and a follow-up >or=12 months. Time to interruption of MPH regular use was analysed by Kaplan-Meier survival analysis. Mean duration of exposure to MPH treatment was computed with the 95% confidence interval (CI).

RESULTS

Annual prevalence of MPH per 1000 persons was 1.1 in 2003, 1.5 in 2004 and 1.8 in 2005 (relative increase of 63.5%). New starters (n = 447) received their first MPH prescription through the hospital (65.1%) or through private practitioners (34.9%). The user profiles were: short (16.6%), occasional (33.8%) and regular (49.6%). Among the new starters, the median time to interruption of MPH regular use was 10.2 months (95% CI: 7.9-12.4). The mean duration of exposure to MPH treatment was: occasional (4.9 months, 95% CI: 4.3-5.5) and regular (25.7 months, 95% CI: 24.6-26.8).

CONCLUSION

Although there is a low prevalence of MPH use in France, this survey revealed a wide profile of users and heterogeneous use patterns.
