Role of Equanimity on the Mediation Model of Neuroticism, Perceived Stress and Depressive Symptoms

The psychometric properties of the Thai version of the Zuckerman-Kuhlman-Aluja personality questionnaire

The Five-Factor Model of personality traits has consistently demonstrated expected associations with features of psychiatric disorders, both within the general population and clinical settings. In pursuit of a more nuanced understanding, facet-level assessments like the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) offer more profound insights into their facets. However, notably, the applicability of the ZKA-PQ to the Thai population remains untested. We hypothesized that the Thai version of the ZKA-PQ would demonstrate the validity of the construct as the original version. Consequently, we enrolled 1,382 participants, 71.3% female, with a mean age of 29.04 years (SD = 10.46). The assessments included the ZKA-PQ, the Perceived Stress Scale, the Core Symptom Index-Depression, and the Neuroticism Inventory. Our findings supported the ZKA-PQ's overarching personality traits but not at the facet level. Aligned with observations in non-Western cultures, it became evident that the Sensation Seeking and Activity facets exhibited sensitivity to the Thai population's dynamics. In light of these outcomes, further exploration is merited to enhance the appropriateness of the Thai ZKA-PQ. This pursuit could illuminate cultural nuances that shape personality traits and their interplay within the Thai context.

Depression and Associated Factors Among Patients with Spinocerebellar Ataxia

Background and Objectives: Spinocerebellar ataxia (SCA) is a progressive neurodegenerative disease often accompanied by depression. This cross-sectional study investigated the prevalence of depression and the associated mental health factors in SCA patients. Material and Methods: Eleven Thai SCA patients completed questionnaires assessing depression, anxiety, inner strengths, perceived social support, personality traits and perceived stress. Results: Participants' average age was 50.27 years old. The prevalence of depression was 27.27%. Depression scores were positively correlated with OI-anxiety score (r = 0.887, 95%CI 0.586 to 0.968), perceived stress (r = 0781, 95%CI 0.305 to 0.936) and personality traits including aggression (r = 0.73, 95% CI 0.197 to 0.920), activity (r = 0.651, 95%CI 0.052 to 0.893) and neuroticism (r = 0.80, 95% CI 0.351 to 0.942). Conversely, depression negatively correlated with inner strengths (r = -0.70, 95%CI -0.910 to -0.139) and perceived social support, particularly from family (r = -0.88, 95%CI -0.966 to -0.564). Conclusions: These findings highlight the need for comprehensive mental health assessment and intervention in SCA patients. Strengthening inner strengths, promoting social support, and managing negative mental health factors may improve quality of life for patients with SCA.

The Relationship Between Feelings of Emptiness and Self-Harm Among Thai Patients Exhibiting Borderline Personality Disorder Symptoms: The Mediating Role of the Inner Strengths

Background and Objectives: Fifty percent of individuals with borderline personality disorder (BPD) experience self-harm. One of the crucial factors related to self-harm is feelings of emptiness. While inner strengths, such as the Five Precepts, meditation, and equanimity, have been identified as potential buffers against negative mental health outcomes in BPD, their role in mediating the relationship between feelings of emptiness and self-harm is not well-documented. This study aimed to explore how these inner strengths mediate the relationship between feelings of emptiness and self-harm in individuals exhibiting BPD symptoms. Materials and Methods: A total of 302 Thai participants exhibiting BPD symptoms completed several assessments: the SCID-II Personality Disorder Questionnaire for BPD to assess feelings of emptiness and self-harm, the Inner-Strength-Based Inventory (i-SBI) to evaluate the Five Precepts, meditation, and equanimity, and the Outcome Inventory Depression (OI-Depression) to assess depression. Mean and standard deviation were used for continuous variables, such as age and OI-Depression. A t-test assessed mean differences in continuous variables between the self-harm group and the non-self-harm group. Chi-square tests examined differences in categorical variables with three or more levels, such as education. Pearson's correlation and linear regression analyzed relationships between continuous variables, including i-SBI and OI-Depression scores. Mediation analysis was performed using IBM SPSS and AMOS, with self-harm as the outcome variable, feelings of emptiness as the predictor, and inner strengths as mediators. Results: The participants had a mean age of 36.56, with 65.4% being female. The analysis showed that the Five Precepts, meditation, and equanimity significantly mediated the relationship between feelings of emptiness and self-harm, with a standardized coefficient of β = 0.534 (95% CI = 0.417 to 0.647, p < 0.001). The indirect effect of feelings of emptiness through these inner strengths was significant (β = 0.034, 95% CI = 0.009 to 0.075, p = 0.005). The mediation model explained 38% of the variance in self-harm with a 3% increase, albeit small but significant. Conclusions: This study highlights that inner strengths negatively mediate the relationship between feelings of emptiness and self-harm, indicating that as these inner strengths increase, the direct impact of feelings of emptiness on self-harm decreases. These findings suggest that targeting inner strengths as protective factors could be a valuable strategy in developing interventions aimed at reducing self-harm by addressing the underlying emotional challenges associated with BPD.

Psychometric Properties of the Chinese Version of the Core Symptom Index: A Study among Chinese Parents of Children with Autistic Spectrum Disorders

(1) Background: Parents of children with autism spectrum disorders often experience psychological distress, which can affect the quality of childcare they provide. It is crucial to screen for psychiatric symptoms among these parents. The core symptom index (CSI) is a widely recognized tool used to assess general symptoms, including depression, anxiety, and somatic issues. It has proven validity and reliability across diverse Thai populations. Given the cultural similarities between Thai and Chinese populations, the CSI has been successfully implemented within the Chinese population. Nevertheless, it is crucial to research its validity and reliability in the general Chinese population. This study aimed to investigate the psychometric properties of the Chinese version of the CSI among parents of children with autism spectrum disorders using confirmatory factor analysis (CFA). (2) Methods: A total of 794 Chinese parents raising children with autism participated in this study. All completed the CSI, along with the social inhibition subscale of the Interpersonal Problems Inventory and the Couple Satisfaction Index. Factorial validity was assessed using CFA to determine how well the bifactor three-factor model fits the data. Various structural models were compared using model fit indices. Convergent and discriminant validity were examined by exploring correlations with the social inhibition subscale and the Couple Satisfaction Index. Invariance testing of the CSI was conducted across multiple groups based on gender, age, and education using CFA. The reliability of the CSI was evaluated using McDonald's omega coefficients. (3) Results: The bifactor model emerged as the best-fitting model for the data, suggesting that the total score of the CSI adequately represents overall psychiatric symptoms. The CSI exhibited significant correlations with the social inhibition subscale (r = 0.41, p < 0.01) and smaller correlation coefficients with the Couple Satisfaction Index (r = -0.16, p < 0.05), indicating both convergent and discriminant validity. The invariant test results support scalar invariance levels based on gender and age but only partial invariance for education. The Chinese version of the CSI demonstrated high consistency, with McDonald's omega coefficients ranging between 0.86 and 0.95. (4) Conclusions: The bifactor model of the Chinese version of the CSI is validated, making it a suitable tool for measuring depression, anxiety, and somatization symptoms among parent(s) of children with autism spectrum disorders. Further research on other Chinese populations is encouraged.

Depression and Its Associated Factors among Undergraduate Engineering Students: A Cross-Sectional Survey in Thailand

BACKGROUND

Depression is a common mental health problem that can affect everyone at different stages of development. Though the prevalence rate of depression among university students is rising, exploration among engineering students is limited. The aim of the study was to examine the prevalence of depression and its associated factors of among engineering students in Thailand.

METHODS

A total of 346 students participated in this study. All completed the outcome inventory depression subscale (OI-D) to evaluate the level and prevalence of depression. Other variables assessed included social skills, learning styles, relationship satisfaction, interpersonal difficulty, alcohol use, internet addiction, and neuroticism. Correlation and regression analyses were applied to test the association between sociodemographic and psychosocial factors and depression.

RESULTS

Of the 346 students with the mean age of 20.25 (SD, 1.33), 52.31% were male. Based on the OI-D, 35.3% of participants exhibited symptoms indicative of major depression. Multiple regression showed that only neuroticism, interpersonal difficulties, social skills, and self-esteem appeared to be the significant predictors of depression.

CONCLUSION

The prevalence of depression among engineering students in Thailand was unexpectedly high compared with the prevalence of depression among engineering students in some other countries. Intra- and interpersonal factors were found to be associated with depression. Further study on identifying these risk factors should be encouraged.

Factors Associated with Depression in Infertile Couples: A Study in Thailand

BACKGROUND

Infertility can affect a couple's mental health and marital and social relationships. The study aimed to investigate the prevalence of depression among infertile couples and their relationships with other factors.

METHODS

This study employed a cross-sectional survey. Validated tools were used to assess anxiety and depression, marital satisfaction, personality traits and sufficiency economy. The actor-partner interdependence model (APIM) was used for dyadic analysis.

RESULTS

The prevalence of depression in infertile couples was 6.7%. Aggression, extraversion and neuroticism were significantly correlated with depression, whereas the expectation of having children, marital satisfaction and sufficiency economy were negatively correlated with depression. The APIM model suggested that neuroticism and marital satisfaction were significant predictors of depression. Partner effect between the expectation of having children and depression was observed (p = 0.039).

CONCLUSIONS

Like other populations, depression in infertile couples seems to be associated with aggression, extraversion and neuroticism. However, there are specific variables related to infertility that impact the depression levels of these couples. For instance, the expectation of having children can affect the partners of infertile couples, while the role of the sufficiency economy is a new factor that has been examined for depression in this sample and requires further exploration.

Moderating role of observing the five precepts of Buddhism on neuroticism, perceived stress, and depressive symptoms

PURPOSE

Evidence has shown that the Five precepts significantly affect the relationship between attachment and resilience; however, little is known whether observing the Five Precepts would help reduce depressive symptoms among those who experience risks. The aim of this study was to examine the moderating role of the Five Precepts in the mediation model relationship among neuroticism, perceived stress, and depression.

PATIENTS AND METHODS

The study employed a cross-sectional survey design and data were collected from the end of 2019 to September 2022 in Thailand. In all, 644 general participants completed questionnaires on the Neuroticism Inventory (NI), the 10-item Perceived Stress Scale (PSS), Depression Subscale, and the Five-Precept Subscale of the Inner Strength-based Inventory (SBI-PP). Mediation and moderation analyses with 5000 bootstrapping methods were used.

RESULTS

Among all, 74.2% were female, and the mean age totalled 28.28 years (SD = 10.6). SBI-PP was shown to have a moderation effect on the relationship between NI, PSS and depressive symptoms. The moderating effect between SBI-PP and PSS was significant, whereas SBI-PP and NI was not. The index of moderated mediation from the Five Precepts was significant (b = -0.019 (95%CI -0.029, -0.009)). The moderated mediation model increased the percent variance explaining depressive symptoms to 47.6%, compared with 32.6% from the mediation model alone.

CONCLUSION

Observing the Five Precepts offers evidence that it buffers the effect of perceived stress on depression. People with high levels of observing the Five Precepts are less likely to develop depressive symptoms. Implications as well as possible future research are discussed.

Buffering Effect of Perseverance and Meditation on Depression among Medical Students Experiencing Negative Family Climate

Background and objective: Thirty percent of Thai medical students experienced depression. Two of the crucial factors related to depression involved borderline personality disorder symptoms and adverse family experiences, while positive strengths were documented to prevent depression. This study aimed to investigate the role of perseverance and meditation on depression; Methods: Two hundred and forty−three medical student participants completed the following measurements: the core symptom index (CSI−D) to measure depression, the family climate questionnaire to measure family experience, the personality disorder questionnaire to measure borderline personality disorder symptoms, and the inner strength−based inventory to measure perseverance and meditation. In the analysis, depression served as an outcome, adverse family climate as a predictor and borderline personality disorder symptoms as a mediator. In contrast, perseverance and meditation were moderators in the mediation model. Mediation and moderation analysis using PROCESS was applied for testing the direct and indirect effects; Results: Among all, 49.38% were male, and the mean age was 22.76 years. Borderline personality disorder symptoms significantly mediated the relationship between adverse family climate and depression, B = 0.0608 (95%CI, 0.0301 to 0.1052). The variance explained by the mediation model was 43%. Meditation moderated the relationship between adverse family climate and borderline personality symptoms, whereas perseverance and meditation were found to be significant moderators for borderline personality disorder symptoms and depression. With two moderators in the mediation model, the indirect effect index was B = 0.0072 (95%CI, 0.0002 to 0.0160). The 49% of variances of depression were explained by the moderated mediation model; Conclusion: Borderline personality disorder symptoms are a crucial variable involving depression. Meditation practice has been demonstrated to be a buffer between negative family climate to borderline personality disorder symptoms and depressive symptoms, whereas perseverance buffers the effect of borderline personality disorder symptoms of depression. Further research on cultivating meditation and perseverance should be encouraged among those with negative family experiences.

Factors Associated with Anxiety and Depression in Infertile Couples—Study Protocol

(1) Background: Infertility refers to the failure to achieve a pregnancy after 12 months or more of regular unprotected sexual intercourse. Infertility is an important medical and social problem that causes individual distress, family conflict and emotional impact experienced by about 15% of couples worldwide. Anxiety and depression are the main psychological problems associated with infertility with many potential contributing factors which are yet to be fully elucidated. This study aims to investigate factors related to anxiety and depression among infertile couples. (2) Methods/Design: This study will employ an analytical cross-sectional survey. Sociodemographic information will be collected. Validated tools will be used to assess anxiety and depression (Outcome Inventory-21(OI-21), marital satisfaction (ENRICH Marital Satisfaction Scale, sufficiency economy (Sufficiency Economy Scale (SES) and personality traits (Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ). The Actor-Partner Interdependence Model estimated by multilevel modeling will be used for dyadic analysis. (3) Discussion: This study will provide evidence about factors associated with anxiety and depression in infertile couples. Outcomes will raise awareness about mental health problems among infertile couples and guide future research for interventions.

Emotion Self-Regulation in Neurotic Students: A Pilot Mindfulness-Based Intervention to Assess Its Effectiveness through Brain Signals and Behavioral Data

Neuroticism has recently received increased attention in the psychology field due to the finding of high implications of neuroticism on an individual’s life and broader public health. This study aims to investigate the effect of a brief 6-week breathing-based mindfulness intervention (BMI) on undergraduate neurotic students’ emotion regulation. We acquired data of their psychological states, physiological changes, and electroencephalogram (EEG), before and after BMI, in resting states and tasks. Through behavioral analysis, we found the students’ anxiety and stress levels significantly reduced after BMI, with p-values of 0.013 and 0.027, respectively. Furthermore, a significant difference between students in emotion regulation strategy, that is, suppression, was also shown. The EEG analysis demonstrated significant differences between students before and after MI in resting states and tasks. Fp1 and O2 channels were identified as the most significant channels in evaluating the effect of BMI. The potential of these channels for classifying (single-channel-based) before and after BMI conditions during eyes-opened and eyes-closed baseline trials were displayed by a good performance in terms of accuracy (~77%), sensitivity (76–80%), specificity (73–77%), and area-under-the-curve (AUC) (0.66–0.8) obtained by k-nearest neighbor (KNN) and support vector machine (SVM) algorithms. Mindfulness can thus improve the self-regulation of the emotional state of neurotic students based on the psychometric and electrophysiological analyses conducted in this study.
