Examining the moderation and mediation effects of mental toughness on perceived stress and anxiety amongst athletes and non-athletes

Resilience as a moderator of the relationship between stress and different symptom dimensions of depression in adolescents with a history of childhood maltreatment: A multi-wave longitudinal study

BACKGROUND

Although childhood maltreatment is a key risk factor for the development of psychopathology including depression in later life, not all children who have been maltreated subsequently become depressed.

OBJECTIVE

The study aimed to examine the potentially moderating influence of resilience on the relationship between daily stress and different symptom dimensions of depression in adolescents with a history of childhood maltreatment.

PARTICIPANTS AND SETTING

A sample of students (n = 999) aged 12-16 years from middle schools with a history of childhood maltreatment participated in this study.

METHODS

A multi-wave longitudinal study was conducted over 12 months. At baseline, adolescent participants completed standardized self-report measures of resilience, depression, and daily stress. The measures of depression and stress were re-administered every three months for the subsequent 12 months. Multi-level modeling was undertaken to analyze the data.

RESULTS

In adolescents with a history of childhood maltreatment, lower resilience scores were associated with greater increases in depressed affect, absence of positive affect and somatic symptom, but not the interpersonal concerns symptom dimensions of depression following daily stress. Resilience is therefore as one explanation for the discrepant findings regarding the relationship between stress and different symptom dimensions of depression, especially with regard to the stress-related depressive dimensions.

CONCLUSION

Resilience appears to moderate the relationship between daily stress and depression and protect against developing depression in children who have been maltreated. Findings provide potential explanation for the effectiveness of resilience-related therapy in treating depressive symptoms.

The Athlete’s Paradox: Adaptable Depression

We proposed that an athlete’s depressive symptoms may be different from the general population in etiology if considered from the context of a depressive disorder. By shifting focus from a limited notion of symptoms onto a comprehensive model of depression, the full scope of the phenomenon becomes clearer. This paper investigated the relationship between neurotransmitters and allostatic load to explain the incidence of depression among elite athletes. This literature review extensively analyzed exercise-induced neurohormonal imbalance resulting in depressive states among athletes. The research revealed that 5-HTTLPR polymorphism, brain-derived neurotrophic factor (BDNF), extensive psychological demands, social stigma, and overtraining syndrome (OTS) may all contribute to a unique version of depression. The research revealed that the biological standards of athletes differ from those of non-athletes, to the point that the new model may be useful, thereby introducing the new term “Adaptable Depression (AD)” to the literature. This framework suggests a new direction for future research to precisely measure the neurotransmitter-related brain changes that result in “Adaptable Depression” in athletes and to establish a better understanding of the depressive tipping point.
