Depressive symptoms at age 9-13 and chronic disabling fatigue at age 16: A longitudinal study

Early identification of depressive symptoms in school-aged children: Psychometric properties and validation of a new short version of Short Mood & Feelings Questionnaire

BACKGROUND

Depressive mood is a common problem among children in Western countries. Professionals in school and other health services have an important role in identifying children at increased risk for depression. The Short Mood and Feelings Questionnaire (SMFQ) is a widely used screening tool, but its 13 items still make it quite time-consuming to complete. There is an urgent need for a quick and easy-to-complete self-report depressive mood scale for use in school health examinations.

AIM

This paper aims to describe and validate a revised version of SMFQ: FsMFQ-6 is intended as a short screening tool for the early identification of depressive symptoms in children.

METHODS

Nationally representative data (n = 95,725) were drawn from the 2017 School Health Promotion Study. The respondents were fourth- and fifth-grade pupils (aged 10-12) in Finnish primary schools. The data were analysed separately by gender. The construct validity of the scale was studied by principal component analysis and confirmatory factor analysis (CFA), convergent validity by both receiver operating characteristic (ROC) analysis and Spearman's correlation coefficient. Reliability was tested by Cronbach's alpha coefficient.

RESULTS

Principal component analysis yielded a one-component model: the Finnish Short Mood and Feelings Questionnaire 6 (FsMFQ-6). CFA confirmed the validity of FsMFQ-6. Compared with mood at home (AUC = 0.80) and mood at school (AUC = 0.85), overall sensitivity and specificity were optimal at cut-off point 0. Cronbach's alpha coefficient was 0.73, indicating good internal consistency. The results for girls and boys were almost identical.

CONCLUSION

The results confirmed the validity and reliability of FsMFQ-6. FsMFQ-6 recognises depressive mood in children and is suitable for screening depressive symptoms in fourth- and fifth-grade pupils in Finland. However, it is important to pay close attention to children who choose the 'Sometimes' response option more than once, for that can be a sign of depressive symptoms.

Health, Wellbeing, and Prognosis of Australian Adolescents with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS): A Case-Controlled Follow-Up Study

Background: The purpose of this study was to follow-up an Australian cohort of adolescents newly-diagnosed with ME/CFS at a tertiary paediatric ME/CFS clinic and healthy controls over a mean period of two years (range 1–5 years) from diagnosis. Objectives were to (a) examine changes over time in health and psychological wellbeing, (b) track ME/CFS symptomatology and fulfillment of paediatric ME/CFS diagnostic criteria over time, and (c) determine baseline predictors of ME/CFS criteria fulfilment at follow-up. Methods: 34 participants aged 13–18 years (25 ME/CFS, 23 controls) completed standardised questionnaires at diagnosis (baseline) and follow-up assessing fatigue, sleep quality and hygiene, pain, anxiety, depression, and health-related quality of life. ME/CFS symptomatology and diagnostic criteria fulfilment was also recorded. Results: ME/CFS patients showed significant improvement in most health and psychological wellbeing domains over time, compared with controls who remained relatively stable. However, fatigue, pain, and health-related quality of life remained significantly poorer amongst ME/CFS patients compared with controls at follow-up. Sixty-five percent of ME/CFS patients at baseline continued to fulfil ME/CFS diagnostic criteria at follow-up, with pain the most frequently experienced symptom. Eighty-two percent of patients at follow-up self-reported that they still had ME/CFS, with 79% of these patients fulfilling criteria. No significant baseline predictors of ME/CFS criteria fulfilment at follow-up were observed, although pain experienced at baseline was significantly associated with criteria fulfilment at follow-up (R = 0.6, p = 0.02). Conclusions: The majority of Australian adolescents with ME/CFS continue to fulfil diagnostic criteria at follow-up, with fatigue, pain, and health-related quality of life representing domains particularly relevant to perpetuation of ME/CFS symptoms in the early years following diagnosis. This has direct clinical impact for treating clinicians in providing a more realistic prognosis and highlighting the need for intervention with young people with ME/CFS at the initial diagnosis and start of treatment.
