Distress or no distress, that's the question: A cutoff point for distress in a working population

E. M. de Boer A. The association of subjective fit perceptions, distress, emotional exhaustion, and work engagement, with work functioning problems: A cross-sectional study conducted among young construction project management professionals

OBJECTIVES

To investigate the association of subjective fit perceptions, distress, emotional exhaustion, and work engagement, with work functioning, among young construction project management professionals (CPMPs).

METHODS

The research had a cross-sectional design. Dutch young CPMPs (142 participants, age range: 20 to 30 years of age) completed a questionnaire containing general questions recording their demographic characteristics, and instruments recording the following concepts: perceived person-organization fit, perceived person-job fit (including demands-abilities fit and needs-supplies fit), distress, emotional exhaustion, work engagement, and work functioning. Correlation analysis and multiple regression analysis were used to examine the association of fit perceptions, distress, emotional exhaustion, and work engagement, with work functioning.

RESULTS

The correlation analysis indicated that person-organization fit, needs-supplies fit, distress, emotional exhaustion, and work engagement correlated significantly with work functioning problems of young CPMPs. The multiple regression analyses corroborated that needs-supplies fit, distress, and emotional exhaustion related significantly to the work functioning problems of young CPMPs, with the standardized regression coefficients (β) of -0.28, 0.52, and 0.38 (P < .01), respectively. Other than would be expected, the multiple regression analyses also made clear that work engagement does not significantly relate to work functioning problems beyond distress and emotional exhaustion.

CONCLUSIONS

Incongruence between personal needs and job supplies, psychological distress, and emotional exhaustion are central correlates of the work functioning problems of young CPMPs. Occupational health professionals can use these insights to help young CPMPs at work.

An intervention that reduces stress in people who combine work with informal care: randomized controlled trial results

Background

The aim of the research was to examine whether a role-focused self-help course intervention would decrease caregiver stress and distress, and functioning problems, among people who suffer stress because they combine paid work with informal care.

Methods

A pre-registered (NTR 5528) randomized controlled design was applied (intervention vs. wait list control). Participants (n = 128) were people who had paid work and were suffering stress due to their involvement in informal care activities. Participants allocated to the intervention group (n = 65) received the role-focused self-help course. Control group members (n = 63) received this intervention after all measurements. Prior to the random allocation (pre-test), and 1 month (post-test 1) and 2 months (post-test 2) after allocation, all participants completed a questionnaire that measured their caregiver stress (primary outcome), distress, work functioning, negative care-to-work interference and negative care-to-social and personal life interference. Mixed model ANOVAs were used to test the effectiveness of the intervention.

Results

Two months after allocation, the intervention group participants had lower levels of caregiver stress and distress compared with the control group participants. The intervention did not directly resolve impaired work functioning or interference of care with work and social/personal life.

Conclusion

The intervention decreases caregiver stress and distress in people who suffer stress because they combine paid work with informal caring. The intervention (Dutch version) can be downloaded at no cost from www.amc.nl/mantelzorgstress.

The mental health of elite athletes in the United Kingdom

OBJECTIVES

The purpose of this study was to investigate the prevalence of signs of anxiety/depression and distress among a sample of elite athletes in the United Kingdom (UK). A secondary aim was to identify the variables associated with signs of anxiety/depression and distress in the same sample.

DESIGN

A cross-sectional survey was distributed to a sample of elite athletes in the UK.

METHODS

A total of 143 elite athletes completed an online survey that consisted of demographic questions, the Greenhaus Scale assessing career satisfaction, the 12-Item General Health Questionnaire assessing signs of anxiety/depression and a distress screener based on the Four-Dimensional Symptom Questionnaire.

RESULTS

47.8% of the overall sample met the cut-off for signs of anxiety/depression and 26.8% met the cut-off for signs of distress. A significant association was found between gender and signs of distress (x²=8.64, df=1, p=0.003). Career dissatisfaction was a significant independent predictor of signs of anxiety/depression (OR=0.836, p=0.001) and distress (OR=0.849, p=0.003).

CONCLUSIONS

The percentage of a sample of elite athletes in the UK showing signs of anxiety/depression and distress indicate that further cross-sectional research is required to understand the prevalence of mental health issues in the elite athlete population in the UK. Findings indicate that screening elite athletes for career dissatisfaction may support the early detection of signs of anxiety/depression and/or distress. Emphasis should be placed on understanding and improving the mental health of elite athletes in the UK.

Improving work functioning and mental health of health care employees using an e-mental health approach to workers' health surveillance: pretest-posttest study

Background

Mental health complaints are quite common in health care employees and can have adverse effects on work functioning. The aim of this study was to evaluate an e-mental health (EMH) approach to workers' health surveillance (WHS) for nurses and allied health professionals. Using the waiting-list group of a previous randomized controlled trial with high dropout and low compliance to the intervention, we studied the pre- and posteffects of the EMH approach in a larger group of participants.

Methods

We applied a pretest–posttest study design. The WHS consisted of online screening on impaired work functioning and mental health followed by online automatically generated personalized feedback, online tailored advice, and access to self-help EMH interventions. The effects on work functioning, stress, and work-related fatigue after 3 months were analyzed using paired t tests and effect sizes.

Results

One hundred and twenty-eight nurses and allied health professionals participated at pretest as well as posttest. Significant improvements were found on work functioning (p = 0.01) and work-related fatigue (p < 0.01). Work functioning had relevantly improved in 30% of participants. A small meaningful effect on stress was found (Cohen d = .23) in the participants who had logged onto an EMH intervention (20%, n = 26).

Conclusion

The EMH approach to WHS improves the work functioning and mental health of nurses and allied health professionals. However, because we found small effects and participation in the offered EMH interventions was low, there is ample room for improvement.

The mental vitality @ work study: effectiveness of a mental module for workers' health surveillance for nurses and allied health care professionals on their help-seeking behavior

OBJECTIVES

To study the effectiveness of a mental module for workers' health surveillance for health care workers.

METHODS

Nurses and allied health care professionals from one organization were cluster-randomized at ward level to an intervention or control group. The intervention included screening for work functioning impairments and mental health complaints. Positively screened workers were invited to visit their occupational physician. Outcome measures, including help-seeking behavior, work functioning, and mental health, were assessed at baseline, 3-month follow-up, and 6-month follow-up.

RESULTS

An effect of study-group × time interaction on help-seeking behavior was found (P = 0.02). Workers in the intervention group showed less work functioning impairments over time than the control group (P = 0.04).

CONCLUSION

The module can be used to stimulate help seeking from the occupational physician and to improve functioning in workers with mild to moderate work functioning, mental health complaints, or both.

Mental Vitality @ Work--a workers' health surveillance mental module for nurses and allied health care professionals: process evaluation of a randomized controlled trial

OBJECTIVE

To evaluate the process of workers' health surveillance (WHS) targeting work functioning and mental health of health care professionals, alongside a randomized controlled trial comparing two strategies.

METHODS

Nurses and allied health care professionals working in one hospital were invited. Process indicators were assessed using methods such as questionnaires and track-and-trace data.

RESULTS

All participants (32%; N = 369) received screening and personalized feedback. In group 1, 41% went to a preventive consultation with their occupational physician. Protocol adherence of participating occupational physicians (n = 5) was high. They regarded the WHS mental module to be meaningful. In group 2, 16% logged into an e-mental health intervention. Most participants would appreciate a future offer of the WHS.

CONCLUSIONS

The WHS mental module was well received and fitted in the occupational health service activities. Nevertheless, response and compliance should be improved.

Effect of an E-mental health approach to workers' health surveillance versus control group on work functioning of hospital employees: a cluster-RCT

OBJECTIVE

To evaluate an e-mental health (EMH) approach to workers' health surveillance (WHS) targeting work functioning (WF) and mental health (MH) of healthcare professionals in a randomised controlled trial.

METHODS

Nurses and allied health professionals (N = 1140) were cluster-randomised at ward level to the intervention (IG) or control group (CG). The intervention consisted of two parts: (a) online screening and personalised feedback on impaired WF and MH, followed by (b) a tailored offer of self-help EMH interventions. CG received none of these parts. Primary outcome was impaired WF (Nurses Work Functioning Questionnaire), assessed at baseline and after three and six months. Analyses were performed in the positively screened subgroup (i) and in all participants (ii).

RESULTS

Participation rate at baseline was 32% (NIG = 178; NCG = 188). Eighty-two percent screened positive for at least mild impairments in WF and/or MH (NIG = 139; NCG = 161). All IG-participants (N = 178) received part (a) of the intervention, nine participants (all positively screened, 6%) followed an EMH intervention to at least some extent. Regarding the subgroup of positively screened participants (i), both IG and CG improved over time regarding WF (non-significant between-group difference). After six months, 36% of positively screened IG-participants (18/50) had a relevant WF improvement compared to baseline, versus 28% (32/115) of positively screened CG-participants (non-significant difference). In the complete sample (ii), IG and CG improved over time but IG further improved between three and six months while CG did not (significant interaction effect).

CONCLUSIONS

In our study with a full compliance rate of 6% and substantial drop-out leading to a small and underpowered sample, we could not demonstrate that an EMH-approach to WHS is more effective to improve WF and MH than a control group. The effect found in the complete sample of participants is not easily interpreted. Reported results may be useful for future meta-analytic work.

Mental Vitality @ Work: The effectiveness of a mental module for workers' health surveillance for nurses and allied health professionals, comparing two approaches in a cluster-randomised controlled trial

PURPOSE

The aim of this study was to compare two approaches for a worker's health surveillance (WHS) mental module on work functioning and work-related mental health.

METHODS

Nurses and allied health professionals from one organisation were cluster-randomised at ward level to e-mental health care (EMH) (N = 579) or occupational physician care (OP) (N = 591). Both groups received screening and personalised feedback on impaired work functioning and mental health. Positively screened participants received an invitation to follow a self-help EMH intervention, or for a consultation with an OP. The primary outcome was impaired work functioning. Follow-up was performed after 3 and 6 months. Linear mixed models were applied to determine differences. Non-inferiority of the EMH-care approach was demonstrated if the mean absolute improvement on work functioning in the OP-care group was ≤10 points higher than the EMH-care group.

RESULTS

Analyses were performed on the positively screened participants (almost 80 %) (EMH N = 75; OP N = 108) and all participants (EMH N = 98; OP N = 142). Both groups improved over time regarding impaired work functioning. A considerable percentage of participants had improved relevantly at follow-up regarding work functioning (3 months: EMH 30 %, OP 46 %; 6 months: EMH 36 %, OP 41 %) compared to baseline. No statistically significant differences were found between the groups, and the difference did not exceed the pre-defined criterion for non-inferiority.

CONCLUSION

The OP-care approach for a WHS mental module trended towards better performance in targeting work functioning, but our findings indicate that the EMH-care approach was non-inferior. However, the high dropout rate and low compliance to EMH interventions should be taken into account.

Association of work-related stress with mental health problems in a special police force unit

OBJECTIVES

Law and order enforcement tasks may expose special force police officers to significant psychosocial risk factors. The aim of this work is to investigate the relationship between job stress and the presence of mental health symptoms while controlling sociodemographical, occupational and personality variables in special force police officers.

METHOD

At different time points, 292 of 294 members of the 'VI Reparto Mobile', a special police force engaged exclusively in the enforcement of law and order, responded to our invitation to complete questionnaires for the assessment of personality traits, work-related stress (using the Demand-Control-Support (DCS) and the Effort-Reward-Imbalance (ERI) models) and mental health problems such as depression, anxiety and burnout.

RESULTS

Regression analyses showed that lower levels of support and reward and higher levels of effort and overcommitment were associated with higher levels of mental health symptoms. Psychological screening revealed 21 (7.3%) likely cases of mild depression (Beck Depression Inventory, BDI≥10). Officers who had experienced a discrepancy between work effort and rewards showed a marked increase in the risk of depression (OR 7.89, 95% CI 2.32 to 26.82) when compared with their counterparts who did not perceive themselves to be in a condition of distress.

CONCLUSIONS

The findings of this study suggest that work-related stress may play a role in the development of mental health problems in police officers. The prevalence of mental health symptoms in the cohort investigated here was low, but not negligible in the case of depression. Since special forces police officers have to perform sensitive tasks for which a healthy psychological functioning is needed, the results of this study suggest that steps should be taken to prevent distress and improve the mental well-being of these workers.

Psychometric properties of the Nurses Work Functioning Questionnaire (NWFQ)

Objectives

The Nurses Work Functioning Questionnaire (NWFQ) is a 50-item self-report questionnaire specifically developed for nurses and allied health professionals. Its seven subscales measure impairments in the work functioning due to common mental disorders. Aim of this study is to evaluate the psychometric properties of the NWFQ, by assessing reproducibility and construct validity.

Methods

The questionnaire was administered to 314 nurses and allied health professionals with a re-test in 112 subjects. Reproducibility was assessed by the intraclass correlations coefficients (ICC) and the standard error of measurement (SEM). For construct validity, correlations were calculated with a general work functioning scale, the Endicott Work Productivity Scale (EWPS) (convergent validity) and with a physical functioning scale (divergent validity). For discriminative validity, a Mann Whitney U test was performed testing for significant differences between subjects with mental health complaints and without.

Results

All subscales showed good reliability (ICC: 0.72–0.86), except for one (ICC = 0.16). Convergent validity was good in six subscales, correlations ranged from 0.38–0.62. However, in one subscale the correlation with the EWPS was too low (0.22). Divergent validity was good in all subscales based on correlations ranged from (−0.06)–(−0.23). Discriminative validity was good in all subscales, based on significant differences between subjects with and without mental health complaints (p<0.001–p = 0.003).

Conclusion

The NWFQ demonstrates good psychometric properties, for six of the seven subscales. Subscale “impaired decision making” needs improvement before further use.

The associations between psychosocial workload and mental health complaints in different age groups

The objective of the present study was to explore associations between psychosocial workload and mental health complaints in different age groups. A questionnaire was sent to 2021 employees of a Dutch railway company. Six aspects of psychosocial workload (work pressure, mental workload, emotional workload, autonomy, social support from colleagues and social support from supervisors) and three mental health outcomes (work-related fatigue, stress and burnout) were assessed. Associations between the aspects of psychosocial workload (distributed into tertiles) and health complaints were analysed by logistic regression analysis in four age groups (22-35, 36-45, 46-55 and 56-66 years old). In all age groups, worse work pressure was a significant risk factor for having mental health complaints. Worse emotional load in the younger employees and lack of social support in older employees were associated with a higher risk of having mental health complaints. Age-specific preventive measures should be implemented on both individual and group levels. STATEMENT OF RELEVANCE: With an ageing workforce, understanding relationships between age and work-related health ailments is increasingly important. This study found that emotional workload in younger and lack of social support in older employees were associated with a higher risk of mental health complaints. Work pressure was a risk factor in all age groups.

Impaired work functioning due to common mental disorders in nurses and allied health professionals: the Nurses Work Functioning Questionnaire

Purpose

Common mental disorders (CMD) negatively affect work functioning. In the health service sector not only the prevalence of CMDs is high, but work functioning problems are associated with a risk of serious consequences for patients and healthcare providers. If work functioning problems due to CMDs are detected early, timely help can be provided. Therefore, the aim of this study is to develop a detection questionnaire for impaired work functioning due to CMDs in nurses and allied health professionals working in hospitals.

Methods

First, an item pool was developed by a systematic literature study and five focus group interviews with employees and experts. To evaluate the content validity, additional interviews were held. Second, a cross-sectional assessment of the item pool in 314 nurses and allied health professionals was used for item selection and for identification and corroboration of subscales by explorative and confirmatory factor analysis.

Results

The study results in the Nurses Work Functioning Questionnaire (NWFQ), a 50-item self-report questionnaire consisting of seven subscales: cognitive aspects of task execution, impaired decision making, causing incidents at work, avoidance behavior, conflicts and irritations with colleagues, impaired contact with patients and their family, and lack of energy and motivation. The questionnaire has a proven high content validity. All subscales have good or acceptable internal consistency.

Conclusion

The Nurses Work Functioning Questionnaire gives insight into precise and concrete aspects of impaired work functioning of nurses and allied health professionals. The scores can be used as a starting point for purposeful interventions.

The Mental Vitality @ Work study: design of a randomized controlled trial on the effect of a workers' health surveillance mental module for nurses and allied health professionals

BACKGROUND

Employees in health care service are at high risk for developing mental health complaints. The effects of mental health complaints on work can have serious consequences for the quality of care provided by these workers. To help health service workers remain healthy and productive, preventive actions are necessary. A Workers' Health Surveillance (WHS) mental module may be an effective strategy to monitor and promote good (mental) health and work performance. The objective of this paper is to describe the design of a three arm cluster randomized controlled trial on the effectiveness of a WHS mental module for nurses and allied health professionals. Two strategies for this WHS mental module will be compared along with data from a control group. Additionally, the cost effectiveness of the approaches will be evaluated from a societal perspective.

METHODS

The study is designed as a cluster randomized controlled trial consisting of three arms (two intervention groups, 1 control group) with randomization at ward level. The study population consists of 86 departments in one Dutch academic medical center with a total of 1731 nurses and allied health professionals. At baseline, after three months and after six months of follow-up, outcomes will be assessed by online questionnaires. In both intervention arms, participants will complete a screening to detect problems in mental health and work functioning and receive feedback on their screening results. In cases of impairments in mental health or work functioning in the first intervention arm, a consultation with an occupational physician will be offered. The second intervention arm offers a choice of self-help e-mental health interventions, which will be tailored based on each individual's mental health state and work functioning. The primary outcomes will be help-seeking behavior and work functioning. Secondary outcomes will be mental health and wellbeing. Furthermore, cost-effectiveness in both intervention arms will be assessed, and a process evaluation will be performed.

DISCUSSION

When it is proven effective compared to a control group, a WHS mental module for nurses and allied health professionals could be implemented and used on a regular basis by occupational health services in hospitals to improve employees' mental health and work functioning.

Training GP's to use a minimal intervention for stress-related mental disorders with sick leave (MISS): Effects on performance: Results of the MISS project; a cluster-randomised controlled trial [ISRCTN43779641]

OBJECTIVE

To study the effects of a brief patient-stress management training on the performance of general practitioners (GPs).

METHODS

After training in the Minimal Intervention for Stress-related mental disorders with Sick leave (MISS), the performance of 24 GPs was compared with the usual care provided by 22 GPs. Outcome measures in this intervention were: assignment of a diagnosis, taking an activating approach and monitoring the symptoms.

RESULTS

Twenty-three GPs completed the training. Outcomes showed that the training added to a psychosocial diagnosis. Other skills (using a questionnaire to make a diagnosis, handing out information leaflets and monitoring the symptoms) were to some extent improved by the training.

CONCLUSION

The result indicates limited adherence of GPs to the MISS. Only a few components of the training were actually applied after the training, and there is still ample room for improvement.

PRACTICE IMPLICATIONS

More than the current 11h of training are probably needed to change the behaviour of GPs in general. Within educational programmes more attention should be given to the implementation of new behaviour, particularly when it concerns the treatment of patients with stress-related problems.

Validation study of a distress screener

OBJECTIVES

A 3-item screening instrument called the Distress Screener was developed for early identification of distress among employees on sick leave. The Distress Screener consists of three items obtained from the distress subscale of the four-dimensional symptom questionnaire (4DSQ). This study assessed an optimal cut-off point and validated the Distress Screener by relating it to the 4DSQ and to medical diagnoses.

METHODS

171 sick-listed employees filled in the Distress Screener and the 4DSQ (containing four subscales: distress, depression, anxiety and somatisation) and medical diagnoses were obtained from occupational physicians (OPs). The optimal cut-off point was assessed by computing sensitivity and specificity values. Validity was assessed by relating the Distress Screener score to the scores on 4DSQ subscales. In addition scores were compared to mental health medical diagnoses and the degree of similarity between two repeated measurements was obtained.

RESULTS

Using the 4DSQ distress score >10 as reference standard, the optimal cut-off point of the Distress Screener was > or =4. Regarding validity, a high correlation (0.82) existed between the Distress Screener and the 4DSQ distress subscale and it was significantly different from the correlations with the other 4DSQ subscales. Also a high correlation existed for the test-retest reliability (0.83). Furthermore, a high score on the Distress Screener seemed to be related to the medical diagnosis 'Stress-related complaints'. All low scores seemed to be related to the medical diagnosis 'Other complaints'. Sensitivity (0.85) and specificity (0.78) values, and positive and negative predictive values of the screener were comparable to those of the 4DSQ distress subscale.

CONCLUSIONS

The Distress Screener is a valid instrument for use by the OP during consulting time as a quick scan for early identification of distress in employees on sick leave. The cut-off point > or =4 is useful for early identification of distress in employees on sick leave.

Detecting depressive and anxiety disorders in distressed patients in primary care; comparative diagnostic accuracy of the Four-Dimensional Symptom Questionnaire (4DSQ) and the Hospital Anxiety and Depression Scale (HADS)

Background

Depressive and anxiety disorders often go unrecognized in distressed primary care patients, despite the overtly psychosocial nature of their demand for help. This is especially problematic in more severe disorders needing specific treatment (e.g. antidepressant pharmacotherapy or specialized cognitive behavioural therapy). The use of a screening tool to detect (more severe) depressive and anxiety disorders may be useful not to overlook such disorders. We examined the accuracy with which the Four-Dimensional Symptom Questionnaire (4DSQ) and the Hospital Anxiety and Depression Scale (HADS) are able to detect (more severe) depressive and anxiety disorders in distressed patients, and which cut-off points should be used.

Methods

Seventy general practitioners (GPs) included 295 patients on sick leave due to psychological problems. They excluded patients with recognized depressive or anxiety disorders. Patients completed the 4DSQ and HADS. Standardized diagnoses of DSM-IV defined depressive and anxiety disorders were established with the Composite International Diagnostic Interview (CIDI). Receiver Operating Characteristic (ROC) analyses were performed to obtain sensitivity and specificity values for a range of scores, and area under the curve (AUC) values as a measure of diagnostic accuracy.

Results

With respect to the detection of any depressive or anxiety disorder (180 patients, 61%), the 4DSQ and HADS scales yielded comparable results with AUC values between 0.745 and 0.815. Also with respect to the detection of moderate or severe depressive disorder, the 4DSQ and HADS depression scales performed comparably (AUC 0.780 and 0.739, p 0.165). With respect to the detection of panic disorder, agoraphobia and social phobia, the 4DSQ anxiety scale performed significantly better than the HADS anxiety scale (AUC 0.852 versus 0.757, p 0.001). The recommended cut-off points of both HADS scales appeared to be too low while those of the 4DSQ anxiety scale appeared to be too high.

Conclusion

In general practice patients on sick leave because of psychological problems, the 4DSQ and the HADS are equally able to detect depressive and anxiety disorders. However, for the detection of cases severe enough to warrant specific treatment, the 4DSQ may have some advantages over the HADS, specifically for the detection of panic disorder, agoraphobia and social phobia.
