Depression Anxiety Stress Scales (DASS-21) in International Contexts

The Depression Anxiety Stress Scales (DASS) is a tool used by psychologists to measure negative emotions like depression, anxiety, and stress. It provides individual scores for each emotion and an overall score for general mental health. The DASS is used worldwide in both general and clinical populations. In this chapter, the background of depression, anxiety, and stress is discussed along with the history of the scale’s development and validation. The DASS has been shown to be a reliable and valid measure of these negative emotions. This tool has been translated into several languages and has been tested across different cultures. The importance of measuring negative emotions is significant because it helps clinicians identify and treat mental health problems. The DASS is a useful tool for screening, diagnosing, and monitoring treatment progress for those experiencing such negative emotions

Investigating state and trait aspects of resilience using Generalizability theory

Challenges of modern living such as burden of disease, a global COVID-19 pandemic and workplace stress leading to anxiety and depression raise the importance of psychological resilience. Psychological interventions should increase trait resilience that involves reinforcing state resilience and requires a clear distinction between state and trait aspects of the construct. Generalizability theory is the appropriate method increasingly used to distinguish between state and trait and to establish reliability of psychological assessment. G-theory was applied to examine five major resilience scales completed at 3 time-points by the sample (n = 94) that possess adequate statistical power for such analyses. All five resilience scales demonstrated strong reliability and generalizability of scores across occasions and sample population as expected for a valid trait measure (G > 0.90). However, eight state aspects of resilience were identified from all five resilience scales including adaptation to change; perseverance; self-confidence while facing adversity; self-efficacy; trust in instincts; ability to follow plans; non-reactivity; and ability to plan. State aspects of resilience appear to show more variability and, pending further research, could potentially be a target for resilience-building interventions. All five measures of resilience are useful to assess long-lasting changes in resilience. Development of a state resilience scale is warranted

Enhancing the assessment of gratitude in Mindfulness Research: a Rasch Analysis of the 6-Item Gratitude Questionnaire

Objectives The 6-item gratitude questionnaire (GQ-6) is a widely used measure reported to be reliable and valid under traditional and Rasch investigations. However, recent investigations were inconsistent regarding the item structure of the GQ-6, with three investigations concluding that item 6 be removed. Previous Rasch analyses also did not produce interval conversion tables, a key benefit of this method which provides a means of improving scale accuracy and aligning the scale with the fundamental principles of measurement. Methods A Partial Credit Rasch Model was used to evaluate psychometric properties of the GQ-6 using a combined sample of 663 respondents from the USA (n = 345) and India (n = 318). Results Initial analysis showed significant scale dysfunction, with overall and individual item misfit, local dependency, disordered response thresholds, instances of differential item functioning by age and nationality, along with poor reliability. Through the use of recent advances in the Rasch methodology, locally dependent items were combined into two super-items and the best fit to the Rasch model was obtained with evidence of strict unidimensionality, invariance, and strong reliability. Results indicate the GQ-6 is suitable for individual and group assessment, while also permitting the creation of an ordinal-to-interval conversion algorithm which has been provided here. Conclusions This study confirmed the robust psychometric properties of the GQ-6 after minor modifications and provides a means for clinicians and researchers to improve the accuracy of this widely used measure in mindfulness research and other relevant studies without modification of its original response format

Using Mindfulness to Improve Quality of Life in Caregivers of Individuals with Intellectual Disabilities and Autism Spectrum Disorder: Agency Outcomes for Caregivers and Clients

Objectives: Research suggests that the quality of life of professional caregivers of individuals with intellectual disabilities and autism spectrum disorder can be enhanced through mindfulness-based training. The effects of such training have been evidenced in terms of perceived psychological stress, compassion satisfaction, compassion fatigue (i.e., burnout, secondary traumatic stress), and symptoms of depression. In addition to changes in caregiver personal outcomes, mindfulness-based training may have effects on the quality assurance variables of the agency that employs these caregivers. The aim of the present study was to examine the changes from a systems perspective in terms of quality assurance variables related to caregivers and clients in community-based group homes. Methods: Professional caregivers (n = 216) were randomized into three experimental conditions based on the training they received: mindfulness, psychoeducation, or inservice training-as-usual (control). The effects of the training were assessed in terms of quality assurance indices pertaining to caregivers (progressive discipline, call-ins, days absent, medical referrals, hospitalizations, and caregiver turnover) and clients (learning objectives, behavioral episodes, use of physical restraints, emergency medications [stat], medical emergencies, hospitalizations, aggression to staff, aggression to peers, and level of supervision). Results: Overall, caregivers in the mindfulness group exhibited significantly fewer progressive discipline and call-ins when compared to the psychoeducation and control groups. Caregivers in both the mindfulness and psychoeducation groups exhibited significantly fewer days of absence from work, medical referrals, and caregiver turnover when compared to the control group. There was no difference across the three groups in terms of hospitalizations. Clients under the care of mindfulness-trained caregivers showed significantly greater improvement in completing learning objectives, fewer behavioral episodes, reduced need for physical restraints and stat medication for behavioral episodes, fewer episodes of aggression to peers, and lower levels of supervision when compared to those in the psychoeducation and control groups. Clients did equally well in terms of medical emergencies, hospitalizations, and aggression to staff in the mindfulness and psychoeducation groups when compared to those in the control group. Conclusions: Differential effects of mindfulness training, psychoeducation, and inservice training-as-usual were evident in quality assurance variables related to caregivers and clients. The results suggest that training caregivers in different approaches to self-care may differentially affect not only their clinical status but also at a systems level in terms of quality assurance indices

The impact of a mindfulness app on postnatal distress

Objectives: The present study investigated the effectiveness of an 8-week mindfulness mobile phone app on women's depression, anxiety, stress and mindful attention/awareness in the postnatal period. Methods: The study enrolled 99 mothers of a child under 1 year old, and randomly assigned them to intervention (n = 49, mean age = 31.11, SD = 4.30, years) and control (n = 50, mean age = 31.35, SD = 5.29, years) groups. Multiple regression examined intervention effects on depression, anxiety, stress and mindful attention/awareness measured post-intervention and at 4-week follow-up, controlling for the baseline and post-intervention measurement of the specific outcome, respectively. Results: The intervention group showed significant decreases in depression, anxiety and stress levels and an increase of mindful attention/awareness post-intervention compared to the control group, with medium to large effect sizes after controlling for effects of corresponding variables at baseline. The intervention group showed further decrease in depression and stress levels and an increase in mindful attention/awareness at 4 weeks post-intervention compared to the control group, with small to medium effect sizes, after controlling for effects of corresponding variables at post-intervention. Conclusions: The outcomes of the study suggest that delivery of mindfulness via smartphones could be a viable and affordable resource for reducing postnatal depression, anxiety and stress
