Depression Anxiety Stress Scales (DASS-21): Factor Structure in Traumatic Brain Injury Rehabilitation

The Depression Anxiety Stress Scales for Youth (DASS-Y): evidence of validity and cross-national and gender measurement invariance

The Depression Anxiety Stress Scales for Youth (DASS-Y) is a recently developed measure of unpleasant emotional experiences for children and adolescents; however, the evidence for its validity is still limited. The present study evaluated the evidence for the structural, convergent, and incremental validity of the DASS-Y on a sample of Serbian adolescents aged 15-19 years (N = 421; 48% female, mean age = 16.86). Measurement invariance across gender and two countries (Serbia and Australia) was also tested. The findings supported the bifactor exploratory structural equation modeling (bifactor-ESEM) representation of the DASS-Y, which includes the General factor of negative affect/emotional distress, and three specific factors of Depression, Anxiety, and Stress. The DASS-Y factors showed evidence of incremental validity in predicting global externalizing symptoms and demonstrated convergent validity in relation to measures of global internalizing and externalizing symptoms as well as subjective well-being. The bifactor-ESEM model of the DASS-Y was found to be invariant across gender and two countries. The present study findings highlight the importance of distinguishing between general and specific components of unpleasant emotional states.

Exploring emotional distress symptom clusters in young adults with childhood traumatic brain injury

BACKGROUND

Depression, anxiety, and stress are persistent and co-occurring symptoms in survivors of childhood traumatic brain injury (TBI), and often impact on health-related quality of life (HRQoL). This paper explored emotional distress symptom clusters and associated factors in young adults with childhood TBI.

METHODS

We included 54 young adults who sustained mild (n = 14), moderate (n = 27), and severe (n = 13) childhood TBI, at 20 years post-injury. The Depression Anxiety Stress Scale was administered. Cluster group membership was identified using two-step clustering and hierarchical clustering methods, and associated factors were assessed with multiple regression models.

RESULTS

Two symptom cluster groups were identified, including a No Distress (n = 66%) and an Elevated Distress (n = 33%) group, with the latter showing significantly higher symptoms of depression, anxiety, and stress (all p < .001). Elevated Distress group membership was linked to tobacco use and poor sleep quality, while poor HRQoL was associated with younger age at injury and Elevated Distress group membership.

CONCLUSIONS

Using cluster methodology, we showed that one-third of young adults with childhood TBI had elevated emotional distress symptoms. This underscores the complex emotional profile of this subgroup and the need for assessment, analysis, and treatment methods that target a range of symptoms rather than relying on single-diagnostic protocols.

Factors Associated with Device, Internet and Videoconferencing Use Amongst Individuals with Moderate-to-Severe Traumatic Brain Injury

Videoconferencing (VC) has the potential to improve access to quality healthcare for individuals with traumatic brain injury (TBI) who require intensive and ongoing rehabilitation post-injury. Gaps in information and communication technology (ICT) use, access, and skills, however, may undermine equitable participation in remotely delivered healthcare and rehabilitation. This cross-sectional study sought to identify which demographic, injury-related, and psychological factors are associated with gaps in digital inclusion amongst individuals with a TBI. Between March 2020 and December 2023, 186 adults with a moderate-to-severe TBI who were aged 18-65 years and were within five years post-injury completed a range of self-report measures. The results demonstrated that most individuals with a moderate-to-severe TBI reported high levels of technology skills and access and used the internet from multiple devices daily. While injury severity was unrelated to technology use, this finding may reflect an overestimation of technology use amongst individuals with the most severe injuries, who were excluded from the study. Several demographic and psychological factors were found to predict VC readiness and are presented within a model to guide clinicians considering client suitability for VC rehabilitation. The current findings indicate that the use of VC in clinical settings following a moderate-to-severe TBI is feasible and suggest that individuals with a TBI may benefit from the greater provision of remotely delivered healthcare than is currently offered.

Perceived vocational support needs and return-to-work outcomes in the first 12-months post-discharge in individuals with acquired brain injury and spinal cord injury: A retrospective cohort study

BACKGROUND

Return-to-work (RTW) is often viewed as an important outcome following acquired brain injury (ABI) and spinal cord injury (SCI), although not all individuals have vocational goals and many experience barriers to RTW.

OBJECTIVE

This study investigated the relationship between RTW and psychosocial functioning at 12-months post-discharge after ABI and SCI and examined patterns of RTW according to perceived need for and receipt of vocational support.

METHODS

A file audit was conducted for 69 participants with ABI (n = 44) and SCI (n = 25). Data on employment status and perceived vocational support at 3- and 12-months post-discharge, home and community participation, psychological distress, and health-related quality of life were extracted.

RESULTS

Individuals in paid employment at 12-months post-discharge (22%, n = 15) reported significantly better psychosocial functioning at this timepoint compared to those not employed (78%; n = 54). For those not employed, three subgroups were identified: 1) Did not perceive the need for or receive vocational support (50%; n = 27); 2) Perceived vocational support needs were unmet (19%; n = 10); and 3) Perceived and received vocational support (31%; n = 17). Psychological distress was highest for those who perceived and received vocational support but were not employed.

CONCLUSION

RTW was associated with better psychosocial functioning after acquired neurological injury. The findings highlight the need for clinicians to explore and revisit individuals' perceived need for and preferences for vocational support and monitor the psychological well-being of those with RTW goals that are not yet successful.

What is the relationship between alexithymia and experiential avoidance? A latent analysis using three alexithymia questionnaires

Alexithymia is a clinically relevant personality trait characterized by poor emotional awareness and associated with several psychological and physical health concerns. Individuals with high alexithymia tend to engage in experiential avoidance and this may mediate psychological distress. However, little is known about what specific processes of experiential avoidance are involved, and the nature of the relation between alexithymia, experiential avoidance, and psychological distress remains unclear at a latent construct level. To examine this relationship at the latent construct level, a representative sample of 693 U.S. adults completed alexithymia (TAS-20, BVAQ, PAQ), general distress (DASS-21), multi-dimensional experiential avoidance (MEAQ), and general health (PROMIS-G-10) questionnaires. Structural equation modeling revealed that alexithymia significantly predicted experiential avoidance (β = 0.966, t = 82.383, p < .01), experiential avoidance significantly predicted general distress (β = 0.810, t = 2.017, p < .05), and experiential avoidance fully mediated the relationship between alexithymia and general distress (βindirect = -0.159, t = -0.398, p > .05). Correlations between alexithymia and experiential avoidance subfactors revealed a strong relationship to the repression and denial subfactor. Experiential avoidance is a promising target for clinical interventions, though longitudinal research is necessary to elucidate how the relationship between alexithymia and experiential avoidance unfolds over time.

Preliminary efficacy and predictors of response to a remotely-delivered symptom self-management program for persistent symptoms after concussion

BACKGROUND

More than a quarter of adults with concussion endure prolonged symptoms of >3 months. We developed the Concussion Education Self-Management program to help people manage persisting symptoms. Here, we assess feasibility, preliminary efficacy, and correlates of response.

METHODS

N = 80 adults participated in the program; ages ranged from 18 to 65 years and time post-injury ranged from 6 months to 18 years. Weekly sessions, delivered remotely and in groups, comprised education and strategies for management of cognitive, emotional, and physical symptoms. Primary outcome: Confidence to self-manage symptoms. Secondary outcomes: Quality of life; mood/anxiety/stress. Predictors of response: Self-reported cognitive, emotional and physical symptoms at intake.

RESULTS

Pre- to post-program improvements were observed in confidence to self-manage, p < 0.03; quality of life, p < 0.001; depression, p < 0.001; anxiety, p < 0.001; and stress, p < 0.001. Considering confidence to self-manage, those with fewer cognitive and physical symptoms benefitted more (p's < 0.0005 and p < 0.01, respectively).

DISCUSSION

This program shows promise for improving self-management of prolonged symptoms. Those with high symptom burden may need extra sessions to benefit. This is a cost-effective and scalable program that can reach people regardless of geographic location or impediments to travel.

Bifactor analysis of the Hospital Anxiety and Depression Scale (HADS) in individuals with traumatic brain injury

Anxiety and depression symptoms are commonly experienced after traumatic brain injury (TBI). However, studies validating measures of anxiety and depression for this population are scarce. Using novel indices derived from symmetrical bifactor modeling, we evaluated whether the Hospital Anxiety and Depression Scale (HADS) reliably differentiated anxiety and depression in 874 adults with moderate-severe TBI. The results showed that there was a dominant general distress factor accounting for 84% of the systematic variance in HADS total scores. The specific anxiety and depression factors accounted for little residual variance in the respective subscale scores (12% and 20%, respectively), and overall, minimal bias was found in using the HADS as a unidimensional measure. Further, in a subsample of 184 participants, the HADS subscales did not clearly discriminate between formal anxiety and depressive disorders diagnosed via clinical interview. Results were consistent when accounting for degree of disability, non-English speaking background, and time post-injury. In conclusion, variance in HADS scores after TBI predominately reflects a single underlying latent variable. Clinicians and researchers should exercise caution in interpreting the individual HADS subscales and instead consider using the total score as a more valid, transdiagnostic measure of general distress in individuals with TBI.

A systematic review of mood and depression measures in people with severe cognitive and communication impairments following acquired brain injury

AIM

A systematic review to identify which mood and depression measures are valid for use with people with severe cognitive and communication impairments following severe acquired brain injury.

METHOD

A systematic search of Cochrane, Web of Science, Ovid, and EBSCOhost was performed in March 2020, July 2021, and September 2022. The search focused on self-report and observer-rated assessment tools used to assess mood, depression, and/or distress in those described as having a severe acquired brain injury. Psychometric properties were extracted using the Consensus-based standards for the selection of health measurement instruments (COSMIN) risk of bias checklist. Qualitative synthesis was performed on extracted patient data.

RESULTS

Nineteen papers detailing the psychometric properties of 25 measures were included, involving 2,914 participants. Nine papers provided details confirming the severity of participants' cognitive and communication impairments. The remaining papers described including severely injured participants but provided limited details so that precise level of severity could not be confirmed. Only one paper showed evidence of adequate psychometric properties and included those with severe cognitive impairments in a study of two observer-rated measures, the Stroke Aphasia Depression Questionnaire (10 items) and the Aphasia Depression Rating Scale.

CONCLUSIONS

Due to the exclusion of individuals with severe cognitive and communication consequences following brain injury, no studies using self-report measures showed adequate validity evidence to recommend their use in this population. A small study using two observer-rated scales included those with severe cognitive impairments and showed satisfactory evidence that these measures can be validly used with this population.

Use of the Depression Anxiety Stress Scale-21 in young people with temporomandibular disorders: Reliability and dimensionality

OBJECTIVE

The reliability and dimensionality of the Depression Anxiety Stress Scale-21 (DASS-21) were explored in adolescents/young adults with temporomandibular disorders (TMDs).

METHODS

TMD presence was established with the Fonseca Anamnestic Index. Reliability of the DASS-21 for participants with (WT) and without (NT) TMDs was assessed by the Cronbach alpha test, while dimensionality was examined using exploratory factor analysis.

RESULTS

Data from 400 participants (mean age 18.8 ± 1.5 years; 52.2% women) comprising 47.0% with and 53.0% without TMDs were evaluated. Total-DASS and the 3 subscales showed acceptable to high internal consistencies for the WT and NT groups, with alphas of 0.78-0.94 and 0.66-0.92, respectively. Although 3 factors contributed to about half the variance for both groups, scalar and item discrepancies in the primary anxiety-stress factor existed.

CONCLUSION

The DASS-21 has good reliability but may comprise only 2 dimensions, specifically anxiety-stress and depression, instead of the 3 originally asserted.

Is Overparenting Associated with Adolescent/Young Adult Emotional Functioning and Clinical Outcomes Following Concussion?

Overparenting (O-P), or "helicopter" parenting, has warranted increased attention across the past decade. It is characterized as being overly involved, protective, and low on granting autonomy, and is associated with deleterious psychosocial outcomes outside of the concussion literature. This study examined the association of overparenting and patient emotional distress and clinical outcomes (i.e., symptoms, neurocognitive test scores, recovery time) post-concussion. Adolescents/young adult concussion patients (injury < 30 days) and parents (N = 101 child-parent dyads) participated. Patient participants completed measures of depression, anxiety, stress, and concussion clinical outcomes while parents concurrently completed an overparenting measure. Results of a general linear model found that overparenting was associated with higher anxiety and stress report of the child. Overparenting had a significant positive correlation with concussion recovery, although of a small magnitude. Emotional distress level, but not overparenting, was moderately associated with worse performance on clinical outcomes, including neurocognitive testing, vestibular/ocular motor dysfunction, and concussion symptom severity.

Lower post-injury psychological resilience is associated with increased recovery time and symptom burden following sport-related concussion

The purpose of this study was to compare athletes with high and low resilience scores on concussion outcomes, and identify significant predictors associated with protracted recovery (>30 days). Forty-five adolescent and young adult athletes (28 males; aged 15.13 ± 2.74; range of 11-22) were diagnosed with an SRC within 14 days of injury (M = 4.9 days) and grouped as high or low resilience based on score on the Connor-Davidson Resilience Scale-10 (CD-RISC-10). Primary dependent measures included days to full clearance, Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT), Depression Anxiety and Stress Scale-21 (DASS-21), and Vestibular/Ocular Motor Screening (VOMS). The low resilience group (n = 22) had a longer recovery (36.0 ± 27.6 vs 17.8 ± 11.2 days), endorsed more mood symptoms (PCSS Affective cluster; 3.8 ± 0.8 vs 0.9 ± 0.7), and were more likely to have VOMS scores above cut off (p = 0.01-0.02), compared to those with high psychological resilience (n = 23). Logistic regression found low resilience scores was the only significant predictor for protracted recovery among injury characteristics and risk factors. Psychological resilience is a critical factor associated with recovery time following sport-related concussions. Low resilience was also associated with other poor clinical outcomes, greater subjective symptom report, more severe vestibular dysfunction, and elevated levels of mood symptoms following injury.

Interdisciplinary Rehabilitation for Concussion Recovery (i-RECOveR): protocol of an investigator-blinded, randomised, case series with multiple baseline design to evaluate the feasibility and preliminary efficacy of a 12-week treatment for persistent post-concussion symptoms

BACKGROUND

Up to 25% of concussed individuals experience persistent post-concussion symptoms (PPCSs) which may interfere with the return to pre-injury activities and cause significant stress. Given that multiple etiological factors are thought to contribute to PPCSs, an interdisciplinary approach is recommended. This pilot study aims to primarily investigate the feasibility of a novel interdisciplinary treatment for PPCSs. Given this intervention is novel, uncertainty exists in terms of potential recruitment and retention rates, adverse events, and treatment adherence and fidelity. These factors will be explored to inform the feasibility of a phase-2 randomised controlled trial. Preliminary efficacy of this intervention will also be explored.

METHODS

Fifteen individuals with mild traumatic brain injury and PPCSs will receive up to 12 weeks of interdisciplinary treatments including psychology, physiotherapy, and medical interventions. Primary feasibility outcomes including data on recruitment and retention rates and treatment adherence will be explored descriptively. The cognitive therapy rating scale will be used to assess treatment fidelity. A single-case series with multiple baseline design will be used to explore preliminary efficacy. Participants will be randomly assigned to baseline phases of 2, 4, or 6 weeks. Regarding patient-centred secondary outcomes, the Rivermead Post-Concussion Symptoms Questionnaire will be assessed three times a week during baseline and treatment phases. Secondary outcomes also include measures of mood, sleep and fatigue, physical functioning, return to activity, and health-related quality of life. Patient-centred outcomes will be assessed at baseline, pretreatment, post-treatment, and one- and three-month follow-up. Thematic analysis of participant experiences will be explored through qualitative interviews.

DISCUSSION

Results from this trial will inform the feasibility and preliminary efficacy of this interdisciplinary concussion intervention and whether proceeding to a future definitive phase-2 randomised controlled trial is worthwhile. Understanding the end-user perspective of the treatment will also enable modifications to the treatment protocol for future trials to best suit the needs of individuals with PPCSs after mTBI. Outcomes from this trial can be directly translated into community rehabilitation programmes.

Reasons for living, positive psychological constructs and their relationship with suicide ideation in people with moderate to severe traumatic brain injury: A cross-sectional study

Positive psychological constructs such as reasons for living, self-esteem and resilience have previously been shown to act as protective psychological barriers against negative psychological outcomes, including suicide ideation in both clinical populations and the general population. This study aims to explore the positive psychological constructs of reasons for living, self-esteem, resilience and their relationship with suicide ideation and predictors of suicide ideation (depression, hopelessness) for N = 50 people who have a severe TBI and are currently receiving community rehabilitation at Liverpool Brain Injury Rehabilitation Unit (LBIRU), NSW. Results indicated good reliability for the use of the RFLI with people who have TBI, with the most frequently endorsed subscale (range 0-5) being "survival and coping beliefs" (4.7 ± 1.0) and the least frequently being "fear of suicide" (2.2 ± 1.1). The shortened version of the RFLI (BRFLI) also displayed good reliability. Positive psychological constructs (reasons for living, resilience, self-esteem) were all significantly inversely associated with suicide and suicide predictors (depression, hopelessness). This study suggests that positive psychological constructs can act as a buffer against suicide ideation after moderate to severe TBI.

Effectiveness of Pharmacotherapy for Depression after Adult Traumatic Brain Injury: an Umbrella Review

Symptoms of depression are common following traumatic brain injury (TBI), impacting survivors' ability to return to work, participate in leisure activities, and placing strain on relationships. Depression symptoms post TBI are often managed with pharmacotherapy, however, there is little research evidence to guide clinical practice. There have been a number of recent systematic reviews examining pharmacotherapy for post TBI depression. The aim of this umbrella review was to synthesize systematic reviews and meta-analyses of the effectiveness of pharmacotherapy for the management of post TBI depression in adults. Eligible reviews examined any pharmacotherapy against any comparators, for the treatment of depression in adults who had sustained TBI. Seven databases were searched, with additional searching of online journals, Research Gate, Google Scholar and the TRIP Medical Database to identify published and unpublished systematic reviews and meta-analyses in English up to May 2020. A systematic review of primary studies available between March 2018 and May 2020 was also conducted. Evidence quality was assessed using Joanna Briggs Institute Critical Appraisal Instruments. The results are presented as a narrative synthesis. Twenty-two systematic reviews were identified, of which ten reviews contained a meta-analysis. No new primary studies were identified in the systematic review. There was insufficient high quality and methodologically rigorous evidence to recommend prescribing any specific drug or drug class for post TBI depression. The findings do show, however, that depression post TBI is responsive to pharmacotherapy in at least some individuals. Recommendations for primary studies, systematic reviews and advice for prescribers is provided. Review Registration PROSPERO (CRD42020184915).

Opinions and options about COVID-19: Personality correlates and sex differences in two European countries

In the initial months of the COVID-19 pandemic in 2020, we collected data (N = 1,420) from Portugal and Spain in relation to personality (i.e., Dark Triad traits, Big Five traits, religiousness, and negative affect) and attitudes related to COVID-19 about its origins, opinions on how to deal with it, and fear of it. The most pervasive patterns we found were: (1) neurotic-type dispositions were associated with stronger opinions about the origins of the virus and leave people to have more fear of the virus but also more trust in tested establishments to provide help. (2): religious people were less trusting of science, thought prayer was answer, and attributed the existence of the virus to an act of God. We also found that sex differences and country differences in attitudes towards COVID-19 were mediate by sex/country differences in personality traits like emotional stability, religiousness, and negative affect. For instance, women reported more fear of COVID-19 than men did, and this was verified by women’s greater tendency to have negative affect and low emotional stability relative to men. Results point to the central role of neuroticism in accounting for variance in broad-spectrum attitudes towards COVID-19.

Acceptance and commitment therapy for individuals with depressive and anxiety symptoms following acquired brain injury: A non-concurrent multiple baseline design across four cases

Patients with acquired brain injury (ABI) often experience symptoms of anxiety and depression. Until now, evidence-based treatment is scarce. This study aimed to investigate the effectiveness of Acceptance and Commitment Therapy (ACT) for patients with ABI. To evaluate the effect of ACT for people with ABI, a non-concurrent multiple baseline design across four cases was used. Participants were randomly assigned to a baseline period, followed by treatment and then follow-up phases. Anxiety and depressive symptoms were repeatedly measured. During six measurement moments over a year, participants filled in questionnaires measuring anxiety, depression, stress, participation, quality of life, and ACT-related processes. Randomization tests and NAP scores were used to calculate the level of change across phases. Clinically significant change was defined with the Reliable Change Index. Three out of four participants showed medium to large decreases in anxiety and depressive symptoms (NAP = 0.85 till 0.99). Furthermore, participants showed improvements regarding stress, cognitive fusion, and quality of life. There were no improvements regarding psychological flexibility, value-driven behaviour, or social participation. This study shows that ACT is possibly an effective treatment option for people experiencing ABI-related anxiety and depression symptoms. Replication with single case or large scale group studies is needed to confirm these findings.

The effects of personality and attitude on risky driving behaviour among public van drivers: hierarchical modelling

Background

Traffic injuries have become a significant public health problem in low- and middle-income countries. Several studies have examined the role of personality and attitude toward traffic safety in predicting driving behaviors in diverse types of drivers. Few studies have investigated risky behavior among public passenger van drivers. This study aims to identify the predictors of self-reported risky driving behavior among public van drivers.

Method

A total of 410 public van drivers were interviewed at terminal stations in Bangkok. Hierarchical regression models were applied to determine the effects of demographics, personality traits, and attitude on self-reported risky driving behaviors.

Results

The results indicated that drivers with a high education level, more working days, and high scores for normlessness and anger were more likely to report risky driving behaviors (p < 0.05).

Conclusion

The personality traits and attitude toward speeding account for aberrant self-reported risky driving behavior in passenger van drivers. This could be another empirical basis for evidence-based road safety interventions in the context of public transport.

Factors Affecting Jordanian Women's Surgical Treatment Decisions for Early-Stage Breast Cancer

Objective:

This study aimed to assess factors influencing surgical treatment decisions for early-stage breast cancer among Jordanian women.

Methods:

A descriptive correlational survey design was utilized to meet the study objective. A total of 180 Jordanian women diagnosed with unilateral early-stage breast cancer (Stages I–II) were recruited from the radiotherapy departments and outpatient surgical and breast cancer clinics at King Hussein Cancer Center (KHCC). Participants completed a structured questionnaire consisting of the Arabic version of the Depression Anxiety Stress Scale, Breast Surgery Beliefs and Expectations Scale, and the Arabic version of the Control Preference Scale.

Results:

The majority of the participants underwent mastectomy as a definitive surgical treatment (i.e. 67%). Only stage at diagnosis and having a second opinion about surgical treatment options were significantly associated with the type of surgical procedure women opted for. The overwhelming majority of the participants in both groups cited the items of “Minimize the chance of breast cancer coming back” and “Minimize the chance of dying of breast cancer” as very important in their decisions for surgical treatment of unilateral early-stage breast cancer. Women who cited the item “remove breast for peace of mind” as important/very important were more likely to opt for mastectomy than women who cited the item as not important.

Conclusions:

Mastectomy is the preferred surgical treatment option for the majority of Jordanian women diagnosed with unilateral early-stage breast cancer at KHCC.

Measuring psychological flexibility and cognitive defusion in individuals with acquired brain injury

PURPOSE

Acceptance and Commitment Therapy (ACT) is used increasingly for individuals with psychological distress following acquired brain injury (ABI) in different countries. However, questionnaires measuring ACT-processes are often not validated for this patient group and need cross-cultural validation. This study investigated the psychometric properties of the Acceptance and Action Questionnaire for Acquired Brain Injury (AAQ-ABI; measuring psychological flexibility related to thoughts and feelings about ABI) and the Cognitive Fusion Questionnaire (CFQ-7; measuring cognitive defusion).

MATERIALS AND METHODS

Score distribution, reliability, and convergent validity of the AAQ-ABI and the CFQ-7 were examined in Dutch individuals with ABI.

RESULTS

Seventy-three patients with ABI were included. The AAQ-ABI showed good reliability (Cronbach's α = 0.87) and the CFQ-7 excellent reliability (Cronbach's α = 0.97). Both did not show a floor or ceiling effect, nor a skewed distribution. There were strong to moderate correlations between the questionnaires and measures of psychological flexibility, mood, quality of life, and value-driven behavior (AAQ-ABI: r = -0.70-0.81; CFQ-7 = -0.67-0.84). Inter-item total correlations indicate that the questions within each questionnaire measured the same construct (AAQ-ABI: r = 0.40-0.78; CFQ-7: r = 0.84-0.93).

CONCLUSIONS

The current study shows that the Dutch AAQ-ABI and CFQ-7 have acceptable to good psychometric properties when measuring psychological flexibility and cognitive defusion in patients with ABI.

Psychological flexibility in mild traumatic brain injury: an evaluation of measures

PRIMARY OBJECTIVE

In this study, we examined the psychometric properties of measures of psychological flexibility in a mild traumatic brain injury (mTBI) sample.

METHOD AND PROCEDURES

Adults who sustained a mTBI (n = 112) completed the Acceptance and Action Questionnaire - Acquired Brain Injury reactive avoidance subscale (AAQ-ABI (RA). Exploratory factor analysis and Rasch analysis were conducted to evaluate the facture structure, dimensionality, and differential item functioning. Construct validity was determined by correlating the AAQ-ABI (RA) with the Acceptance and Action Questionnaire-Revised (AAQ-II) and Fear Avoidance after Traumatic Brain Injury (FAB-TBI).

MAIN OUTCOME AND RESULTS

The AAQ-ABI (RA) was found to have strong internal consistency (Cronbach's α = 0.87). Consistent with previous findings, the AAQ-ABI (RA) had one distinct factor. Fit to the unidimensional Rasch model was adequate (χ² (18) = 22.5, p = .21) with no evidence of differential item functioning across person factors examined. The AAQ-ABI (RA) also had expected relationships with theoretically relevant constructs.

CONCLUSIONS

The AAQ-ABI (RA) appears to be a psychometrically sound measure of psychological flexibility in mTBI.

The Effect of Transcranial Direct Current Stimulation on Chronic Neuropathic Pain in Patients with Multiple Sclerosis: Randomized Controlled Trial

OBJECTIVE

Chronic neuropathic pain is a common symptom in multiple sclerosis (MS). This randomized controlled single-blinded study investigated whether a new protocol involving five days of transcranial direct current stimulation (tDCS) with an interval period would be effective to reduce pain using the visual analog scale (VAS). Other secondary outcomes included the Neuropathic Pain Scale (NPS), Depression Anxiety Stress Score (DASS), Short Form McGill Pain Questionnaire (SFMPQ), and Multiple Sclerosis Quality of Life 54 (MSQOL54).

DESIGN

A total of 30 participants were recruited for the study, with 15 participants randomized to a sham group or and 15 randomized to an active group. After a five-day course of a-tDCS, VAS and NPS scores were measured daily and then weekly after treatment up to four weeks after treatment. Secondary outcomes were measured pretreatment and then weekly up to four weeks.

RESULTS

After a five-day course of a-tDCS, VAS scores were significantly reduced compared with sham tDCS and remained significantly low up to week 2 post-treatment. There were no statistically significant mean changes in MSQOL54, SFMPQ, NPS, or DASS for the sham or treatment group before treatment or at four-week follow-up.

CONCLUSIONS

This study shows that repeated stimulation with a-tDCS for five days can reduce pain intensity for a prolonged period in patients with MS who have chronic neuropathic pain.

The Adaptation of Pain Assessment Tools from High-Income to Low- and Middle-Income Countries: Psychometric Properties of a Set of Chronic Pain Questionnaires in Mongolian and New Zealand Patient Samples

OBJECTIVE

Chronic pain is a leading cause of disability in low- and middle-income countries; however, pain assessment tools have generally been developed and validated in high-income countries. This study examines the psychometric properties of a set of translated pain (and distress) questionnaires in Mongolia and documents the characteristics of people seeking treatment for chronic pain in Mongolia, compared with those in New Zealand, which is representative of high-income countries.

DESIGN

Cross-sectional, observational.

SETTING

Hospital-based pain treatment centers in New Zealand and Mongolia.

SUBJECTS

People seeking treatment for chronic pain in Mongolia (N = 142) and New Zealand (N = 159).

METHODS

The Brief Pain Inventory, the Depression Anxiety Stress Scale-21, the Pain Catastrophizing Scale, and the Pain Self-Efficacy Questionnaire were translated into Mongolian and administered to patients attending a hospital-based pain service. Questionnaires that were completed by patients in New Zealand were used for comparisons. Internal reliability, convergent validity, and factor structure were assessed in both groups.

RESULTS

Patients in Mongolia were older and reported lower pain intensity, interference, and distress and higher pain self-efficacy than those in New Zealand. The translated questionnaires had good internal consistencies, and the relationships between pain variables were similar across both groups. The factor structure for the Pain Catastrophizing Scale was consistent across both groups, but this was not the case for the Brief Pain Inventory or the Depression Anxiety Stress Scale-21.

CONCLUSIONS

Findings indicate that some pain outcome measures may be appropriate for use in Mongolia and should be investigated in other low- and middle-income countries.

Protocol for a Phase Two, Parallel Three-Armed Non-inferiority Randomized Controlled Trial of Acceptance and Commitment Therapy (ACT-Adjust) Comparing Face-to-Face and Video Conferencing Delivery to Individuals With Traumatic Brain Injury Experiencing Psychological Distress

Background: People with traumatic brain injury (TBI) face a range of mental health challenges during the adjustment process post-injury, but access to treatment can be difficult, particularly for those who live in regional and remote regions. eHealth provides the potential to improve access to evidence-based psychological therapy for people with a severe TBI. The aim of the current study is to assess the efficacy of a psychological intervention delivered via video consulting to reduce psychological distress in people with TBI. Methods: This paper outlines the protocol for a multi-center, three-arm, parallel, non-inferiority randomized controlled trial (RCT) of an evidence-based manualized psychological intervention, ACT-Adjust. ACT-Adjust provides nine sessions for adults with a moderate to severe TBI experiencing clinical levels of psychological distress. Fifty-six participants referred from Brain Injury Rehabilitation Units across New South Wales (NSW) and the NSW icare scheme will be randomly allocated to three conditions; (1) video consulting (VC), (2) face-to-face (FtF) and, (3) a waitlist control (WL). Discussion: This is the first RCT to evaluate the efficacy of a psychological therapy (ACT-Adjust) delivered via video consulting for individuals with a moderate to severe TBI.

Development and Assessment of the Personal Emotional Capital Questionnaire for Adults

(1) Background: The present study developed and evaluated a personal emotional capital questionnaire (PECQ) for adults that assessed 10 domains of personal emotional capital. (2) Method: Initially, 100 items were created and then administered to students attending Semnan University and Semnan University of Medical Sciences in Iran. Of the 700 questionnaires distributed, 527 were completed in full. Students were sampledusing the multi-stage random cluster method. Exploratory factor analyses, Cronbach’s alpha, and test–retest reliability were used to evaluate the scale. (3) Results: The ten components ofthe PECQ were confirmed. Test–retest correlations after 30 days were high, as was Cronbach’s alpha (0.94). Thecomponents highly correlatedwith overall emotional capital. The PECQ displayed convergent validity as it positively correlated with the Keyes’s Mental Health Continuum—Short Form and students’GPAs. The PECQ displayed divergent validity as it negatively correlated with measures of depression, anxiety and stress (Depression Anxiety and Stress Scale (DASS21)). Differences in overall PECQ scores and its components were examined for several variables including gender, age, marital and employment status, academic program, and field of study. PECQ scores were not sensitive to the order of administering questionnaires. (4) Conclusion: The results suggest that the PECQ is a valid and reliable measure of personal emotional capital and supports its use in adults.

Confirmatory Factor Analysis of Three Versions of the Depression Anxiety Stress Scale (DASS-42, DASS-21, and DASS-12) in Polish Adults

Background: The Depression Anxiety Stress Scales (DASS) are designed to identify quickly and differentiate between the symptoms of depression and anxiety in the non-clinical population. Different versions (original and short) were validated in many cultures. Nevertheless, there are no data of factorial validity of the different versions of this scale in Polish culture. Thus, the aim of this study was to evaluate the factor structure using confirmatory factor analysis (CFA) and internal consistency of DASS-42 (original version) and two short versions (DASS-21 items and DASS-12 items) in the Polish population. Methods: The DASS-42 was administered to a non-clinical sample, broadly representative of the general Polish adult population (n = 1,021) in terms of demographic variables. The DASS-21 and DASS-12 version used in this study comprise seven and four items from each of the following corresponding three subscales of the Polish version of DASS-42. Results: There were two models that fitted best for DASS-42: (a) modified three correlated factors (depression, anxiety, and stress) with cross-loadings and (b) second order (general factor of psychological distress) and three factors with cross-loadings. There were also two models that fitted best for DASS-21 and DASS-12: (a) modified three correlated factors (depression, anxiety, and stress) and (b) second order (general factor of psychological distress) and three factors. Conclusions: All three versions of DASS appear to have an acceptable factorial structure. However, the shorter versions (DASS-21 and DASS-12) may be more feasible to use in general medical practice and also be less burdensome to participants.

Are multiple sclerosis patients and their caregivers more anxious and more committed to following the basic preventive measures during the COVID-19 pandemic?

•

MS patients were more anxious, depressed and stressed during the COVID-19 pandemic than their caregivers and the general population.

•

Younger patients, those with high EDSS scores and those who believed that MS patients are at high risk for COVID-19 infection were more anxious.

•

The patients’ knowledge about the factors that may affect the risk for COVID-19 infection was poor.

•

Though they were more anxious, they were not more committed – in contrast to what would be expected - to follow the basic preventive measures for staying safe during the pandemic than the general population.

Background

The novel coronavirus of 2019 (COVID-19), a pandemic of the kind not seen for a century, has caused global apprehension and distress.

Objectives

to evaluate whether the psychological state and behaviours of multiple sclerosis (MS) patients and their caregivers were different from the non-MS population or not during the pandemic.

Methods

A cross-sectional survey was conducted on 115 MS patients, 33 MS caregivers and 129 healthy controls. Depression anxiety stress score-21 (DASS-21) was used for evaluation of their psychological state.

Results

MS patients had significantly higher DASS-21 scores (51.48±29.62) than their caregivers (29.79±27.19) and non-MS population (32.91±23.39) (p = 0.005). Younger patients (r=-0.252, p<0.0001), those with high EDSS scores (r = 0.023, p = 0.013) and those who believed that MS patients are at high risk for COVID-19 infection (p = 0.009) had the highest anxiety scores. There was no difference between the three groups in the level of commitment to staying at home (p = 0.747), wearing facemask (p = 0.164), wearing gloves (0.225), avoiding crowd (p = 0.225) and frequent hand washing (p = 0.570). Anxious patients had more relapses (p = 0.002) and pseudorelapses (p = 0.008).

Conclusion

In this cohort, MS patients were more anxious, stressed and depressed during the COVID-19 pandemic than their caregivers and the non-MS population, but they were not more motivated to follow the basic preventive measures against infection.

Long-term negative emotional outcomes of warzone TBI

OBJECTIVE

Many veterans of the Iraq and Afghanistan Wars have experienced traumatic brain injury (TBI). Although prior work has examined associations between TBI and development of psychiatric syndromes, less is known about associations between TBI and component emotions constituting these syndromes, especially in the long term. The purpose of this study was to examine the long-term emotional consequences of deployment-related TBI.

METHODS

As part of VA Cooperative Studies Program #566, we assessed a sample of n = 456 US Army soldiers prior to an index deployment to Iraq, and again an average of 8.3 years (SD = 2.4 years) after their deployment for a long-term follow-up assessment. In this report, we used adjusted regression analyses to examine the relationship of deployment TBI to depression, anxiety, and stress symptom severity measured at the long-term follow-up assessment. A structured interview was used to determine TBI history; the Depression, Anxiety, and Stress Scale, 21-item version (DASS-21) was used to determine emotional status at the follow-up evaluation.

RESULTS

Warzone TBI events, particularly when greater than mild in severity, were independently associated with depression, anxiety, and stress severity at long-term follow-up, even after taking into account variance attributable to pre-deployment emotional distress and war-zone stress. Post-hoc analyses did not detect independent associations of either number of events or injury mechanism with outcomes.

CONCLUSIONS

These findings highlight the potentially enduring and multi-faceted emotional effects of deployment TBI, underscoring the need for early assessment of negative affectivity in warzone veterans reporting TBI.

Depression, Anxiety and Stress Scales (DASS-21): Construct Validity Problem in Hispanics

The main purpose of this research was to examine the construct validity of the Depression, Anxiety and Stress Scales (DASS-21) in order to determine whether it is able to adequately discriminate between symptoms of depression and anxiety in the Hispanic population in Puerto Rico. This study has an instrumental design. A total of 1073 Hispanics participated in this psychometric study. The results showed that the DASS-21 has serious psychometric deficiencies, especially related to the construct validity, as well as convergent and discriminatory validity. In addition, it was shown that DASS-21 do not replicate the three-dimensional structure of the original instrument in the Hispanic community. Finally, it was confirmed that the DASS-21 have difficulty in properly identifying and discriminating between symptoms associated with depression and anxiety in a Hispanic population.

A Web- and Mobile App-Based Mental Health Promotion Intervention Comparing Email, Short Message Service, and Videoconferencing Support for a Healthy Cohort: Randomized Comparative Study

BACKGROUND

The rapid increase in mental health disorders has prompted a call for greater focus on mental health promotion and primary prevention. Web- and mobile app-based interventions present a scalable opportunity. Little is known about the influence of human support on the outcomes of these interventions.

OBJECTIVE

This study aimed to compare the influence of 3 modes of human support on the outcomes (ie, mental health, vitality, depression, anxiety, stress, life satisfaction, and flourishing) of a 10-week, Web- and mobile app-based, lifestyle-focused mental health promotion intervention among a healthy adult cohort.

METHODS

Participants were recruited voluntarily using a combination of online and offline advertising. They were randomized, unblinded into 3 groups differentiated by human support mode: Group 1 (n=201): standard-fully automated emails (S); Group 2 (n=202): standard plus personalized SMS (S+pSMS); and Group 3 (n=202): standard plus weekly videoconferencing support (S+VCS), hosted by 1 trained facilitator. Participants accessed the intervention, including the questionnaire, on a Web-based learning management system or through a mobile app. The questionnaire, administered at pre- and postintervention, contained self-reported measures of mental well-being, including the "mental health" and "vitality" subscales from the Short Form Health Survey-36, Depression Anxiety and Stress Scale-21, Diener Satisfaction With Life Scale (SWLS), and Diener Flourishing Scale.

RESULTS

Of 605 potential participants, 458 (S: n=157, S+pSMS: n=163, and S+VCS: n=138) entered the study by completing registration and the preintervention questionnaire. At post intervention, 320 out of 458 participants (69.9%; S: n=103, S+pSMS: n=114, and S+VCS: n=103) completed the questionnaire. Significant within-group improvements were recorded from pre- to postintervention in all groups and in every outcome measure (P≤.001). No significant between-group differences were observed for outcomes in any measure: mental health (P=.77), vitality (P=.65), depression (P=.93), anxiety (P=.25), stress (P.57), SWLS (P=.65), and Flourishing Scale (P=.99). Adherence was not significantly different between groups for mean videos watched (P=.42) and practical activity engagement (P=.71). Participation in videoconference support sessions (VCSSs) was low; 37 out of 103 (35.9%) participants did not attend any VCSSs, and only 19 out of 103 (18.4%) attended 7 or more out of 10 sessions. Stratification within the S+VCS group revealed that those who attended 7 or more VCSSs experienced significantly greater improvements in the domains of mental health (P=.006; d=0.71), vitality (P=.005; d=0.73), depression (P=.04; d=0.54), and life satisfaction (P=.046; d=0.50) compared with participants who attended less than 7.

CONCLUSIONS

A Web- and mobile app-based mental health promotion intervention enhanced domains of mental well-being among a healthy cohort, irrespective of human support. Low attendance at VCSSs hindered the ability to make meaningful between-group comparisons. Supplementing the intervention with VCSSs might improve outcomes when attendance is optimized.

The BrainACT study: acceptance and commitment therapy for depressive and anxiety symptoms following acquired brain injury: study protocol for a randomized controlled trial

BACKGROUND

Following an acquired brain injury, individuals frequently experience anxiety and/or depressive symptoms. However, current treatments for these symptoms are not very effective. A promising treatment is acceptance and commitment therapy (ACT), which is a third-wave behavioural therapy. The primary goal of this therapy is not to reduce symptoms, but to improve psychological flexibility and general well-being, which may be accompanied by a reduction in symptom severity. The aim of this study is to investigate the effectiveness of an adapted ACT intervention (BrainACT) in people with acquired brain injury who experience anxiety and/or depressive symptoms.

METHODS

The study is a multicenter, randomized, controlled, two-arm parallel trial. In total, 94 patients who survive a stroke or traumatic brain injury will be randomized into an ACT or control (i.e. psycho-education and relaxation) intervention. The primary outcome measures are the Hospital Anxiety and Depression Scale and the Depression Anxiety Stress Scale. Outcomes will be assessed by trained assessors, blinded to treatment condition, pre-treatment, during treatment, post-treatment, and at 7 and 12 months.

DISCUSSION

This study will contribute to the existing knowledge on how to treat psychological distress following acquired brain injury. If effective, BrainACT could be implemented in clinical practice and potentially help a large number of patients with acquired brain injury.

Behavioural activation therapy to improve participation in adults with depression following brain injury: A single-case experimental design study

Following brain injury, the risk of depression increases. There are few studies of non-pharmacological interventions for this problem. Behavioural Activation (BA) could help because it has been demonstrated to be as effective as cognitive-behaviour therapy but is less cognitively demanding and more suitable for people with brain impairment. The current study evaluated BA using a multiple-baseline design across behaviours with replication. Three male participants with clinically significant depressive symptoms (two with traumatic brain injury aged 26 and 46, one who experienced strokes in infancy, aged 26) engaged in a 10-14-week trial of BA focusing on three activity domains: physical, social and functional activities. Participants completed an online form three times a day which recorded activity participation and responses to a single-item mood scale. There was little evidence in support of BA for increasing participation. There was also a lack of change in average mood, but some positive effects were found on measures of depression symptoms and quality of life in these participants. Various factors affected participation which might have been mitigated by extended treatment contact, greater use of prompts or electronic aids or the addition of other therapy modes.

Systematic review of the measurement properties of the Depression Anxiety Stress Scales-21 by applying updated COSMIN methodology

PURPOSE

The Depression Anxiety Stress Scales (DASS)-21 measures emotional symptoms of depression, anxiety, and stress, is relatively short, and is freely available in the public domain, which has resulted in it being applied to various clinical and non-clinical populations in many countries. The aim of this study was to systematically review the measurement properties of the DASS-21.

METHODS

The MEDLINE, Embase, and CINAHL databases were searched. The methodological quality of each identified study was assessed using the updated COSMIN Risk of Bias checklist. The quality of the measurement properties of the studies was rated using the updated criteria for good measurement properties. The quality of evidence was rated using a modified version of the GRADE approach.

RESULTS

This study included 48 studies in its review. The content validity of the DASS-21 demonstrated sufficient moderate-quality evidence. The instrument exhibited sufficient high-quality evidence for bifactor structural validity and internal consistency. The instrument also showed sufficient high-quality evidence for hypothesis testing of construct validity. Regarding criterion validity, only the DASS-21 Depression subscale demonstrated sufficient high-quality evidence. The measurement invariance across gender demonstrated inconsistent moderate-quality evidence. There was insufficient low-quality evidence for the reliability of each subscale. For responsiveness there was sufficient low-quality evidence for depression and stress subscales, and insufficient very-low-quality evidence for anxiety subscale.

CONCLUSIONS

The DASS-21 demonstrated sufficient high-quality evidence for bifactor structural validity, internal consistency (bifactor), criterion validity (Depression subscale), and hypothesis testing for construct validity. Further studies are required to assess the other measurement properties of the DASS-21.

The 21-Item and 12-Item Versions of the Depression Anxiety Stress Scales: Psychometric Evaluation in a Korean Population

PURPOSE

This study aimed to evaluate the psychometric properties of the Depression Anxiety Stress Scales 21 and 12 in a Korean population.

METHODS

The Depression Anxiety Stress Scales were translated into Korean using a translation and back-translation technique, and the content validity was assessed by an expert panel. Participants were recruited from six community health centers (n = 431) and two community mental health centers (n = 50). A field test of the psychometric properties of the instruments was conducted using confirmatory factor analysis with bootstrap maximum likelihood estimation involving 1,000 samples, Pearson's analysis, t test, and Cronbach's α coefficient.

RESULTS

Confirmatory factor analysis of the Depression Anxiety Stress Scales 21 and 12 supported both three-factor and second-order three-factor models. The Scales 21 and 12 satisfied convergent validity with the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Perceived Stress Scale-10 and discriminant validity with the Rosenberg Self-Esteem Scale. The scores for the Depression Anxiety Stress Scales 21 and 12 were higher for the psychiatric group than for the nonpsychiatric group, confirming the presence of known-groups validity. The Depression Anxiety Stress Scales 21 and 12 exhibited moderate-to-strong correlations with the Negative Affect. Cronbach's α coefficients for the Depression Anxiety Stress Scales 21 and 12 were .93 and .90, respectively.

CONCLUSION

The Depression Anxiety Stress Scales 21 and 12 appear to be acceptable, reliable, and valid instruments. However, the shorter Depression Anxiety Stress Scales 12 may be more feasible to use in a busy practice and also be less burdensome to respondents.
