Work-home interaction from a work psychological perspective: Development and validation of a new questionnaire, the SWING

Abstract This paper reports on the stepwise development of a new questionnaire for measuring work-home interaction, i.e. the Survey Work-home Interaction—NijmeGen, the SWING). Inspired by insights from work psychology, more specifically from Effort-Recovery Theory (Meijman & Mulder, 1998), we defined work-home interaction by differentiating between the direction and quality of influence. Four types of work-home interaction were distinguished and measured by using 22 (including 13 self-developed) items. By using data from five independent samples (total N=2472), validity evidence was provided based on the internal structure of the questionnaire. The results showed that the questionnaire reliably measured four empirically distinct types of work-home interaction, and that this four-dimensional structure was largely invariant across the five samples as well as across relevant subgroups. Validity evidence was also provided based on the relations with external (theoretically relevant) variables (i.e. job characteristics, home characteristics, and indicators of health and well-being). The results generally supported the hypothesized relationships of these external variables with negative work-home interaction. Less support was found, however, for the hypothesized relationships with positive work-home interaction. This contributes to current literature as it employs a relatively broad conceptualization of work-home interaction and offers a promising tool that measures its multiple components across a wide variety of workers.

How fatigued do you currently feel? Convergent and discriminant validity of a single-item fatigue measure

How Fatigued Do You Currently Feel? Convergent and Discriminant Validity of a Single‐Item Fatigue Measure: Madelon L.M. van Hooff, et al. Department of Work and Organizational Psychology, Radboud University Nijmegen, The Netherlands—The main aim of this study was to establish the convergent and discriminant validity of a single‐item measure of daily fatigue (“How fatigued do you currently feel?”) in a daily diary context. Convergent validity of our measure was examined by relating it to a validated multiple‐item measure of fatigue (Profile of Mood States; McNair, Lorr, & Droppelman, 1971) and to other daily (work‐home interference, sleep complaints, work‐related effort) and global (fatigue, health complaints, work‐home interference, job pressure) measures that are conceptually related to fatigue. Discriminant validity was assessed by relating the single‐item fatigue measure to daily (work pleasure) and global (job control, social support, motivation to learn) measures that are conceptually distinct from fatigue. Data were collected among 120 academic staff members, who completed a general questionnaire (tapping the global measures under study) and who took part in a 9‐d daily diary study (3 measurements daily). Correlation patterns and multilevel analyses revealed strong and significant associations between the single‐item fatigue measure and the variables incorporated to assess convergent validity (especially with the POMS: r=0.80), thus supporting the convergent validity of our measure. Relations with variables included to examine discriminant validity were weak or insignificant, supporting the discriminant validity of the single‐item fatigue measure. Despite this studys limitations (i.e., exclusive use of self‐reporting, specific sample) we conclude that this single‐item fatigue measure offers a valid way to assess daily fatigue.

Work–home interference: How does it manifest itself from day to day?

Abstract Although work–home interference (WHI) refers to a process of negative interaction between the work and home domains, little attention has been paid to the actual processes involved in the within-person, day-to-day management of work and home. Therefore, this study investigated if, and how, a global report for the individual, of WHI (i.e., a general indicator of experienced WHI) is reflected in daily reports of WHI, in employees’ daily activity patterns in the work and home domain, and in their daily health and well-being. Effort-Recovery theory (Meijman & Mulder, 1998) provided the theoretical basis for this study. Data were collected among 120 academic staff members (62% male) who completed a general questionnaire, addressing global WHI as well as demographical information, and who also participated in a 5-day daily diary study. WHI was measured using the 8-item WHI subscale of the Survey Work–home Interaction Nijmegen (SWING), with an adapted version being used for the diary studies. Results showed that global WHI: (1) was positively related to daily WHI; (2) was positively related to the time spent daily on overtime work in the evening; (3) was negatively related to the time spent daily on low-effort activities; and (4) was positively related to daily fatigue and sleep complaints. We conclude that Effort-Recovery theory seems promising for the study of WHI, and that diary studies are valuable, as these provide detailed insight into what global reports of WHI actually signify from day to day.

Exercise as an intervention to reduce study-related fatigue among university students: A two-arm parallel randomized controlled trial

Background Many university students experience high levels of study-related fatigue. This high prevalence, and the negative impact of fatigue on health and academic performance, call for prevention and reduction of these symptoms. The primary aim of the current study was to investigate to what extent an exercise intervention is effective in reducing three indicators of study-related fatigue (emotional exhaustion, overall fatigue, and need for recovery). Effects of exercise on secondary outcomes (sleep quality, self-efficacy, physical fitness, and cognitive functioning) were also investigated. Methods Participants were students with high levels of study-related fatigue, currently not exercising or receiving other psychological or pharmacological treatments, and with no medical cause of fatigue. They were randomly assigned to either a six-week exercise intervention (low-intensity running three times a week, n = 49) or wait list (no intervention, n = 48). All participants were measured before the intervention (T0), and immediately after the intervention (T1). Exercisers were also investigated 4 weeks (T2) and 12 weeks (T3) after the intervention. Results Participants in the exercise condition showed a larger decrease in two of the three indicators of study-related fatigue (i.e., overall fatigue and need for recovery) as compared to controls. Additionally, sleep quality and some indicators of cognitive functioning improved more among exercisers than among controls. No effects were found for self-efficacy, and physical fitness. The initial effects of the exercise intervention lasted at follow-up (T2 and T3). At 12-week follow up (T3), 80% of participants in the exercise condition still engaged in regular exercise, and further enhancements were seen for emotional exhaustion, overall fatigue, and sleep quality. Conclusions These results underline the value of low-intensity exercise for university students with high levels of study-related fatigue. The follow-up effects that were found in this study imply that the intervention has the potential to promote regular exercise and accompanying beneficial effects in the longer run.

Systematic review of the association between physical activity and burnout

Burnout constitutes a health risk, and interventions are needed to reduce it. The aim of this study was to synthesize evidence regarding the relationship between physical activity and burnout by conducting a systematic review of longitudinal and intervention studies.

Day-to-day relations between stress and sleep and the mediating role of perseverative cognition

OBJECTIVE The goals of this longitudinal diary-based study were to shed light on the day-level relationship between stress and subsequent sleep, and to examine whether perseverative cognition is a mediating factor in this relation. METHODS A total of 44 Dutch PhD students were followed during a two-month period, from one month before their public thesis defense (ie, a stressful life event), until one month thereafter. Participants completed short evening and morning questionnaires on eight occasions (in anticipation of and following the defense), including questions about day-level stress, sleep quality, and perseverative cognition. Objective sleep parameters were collected with the SenseWear Pro Armband. RESULTS Multilevel analysis was used to analyze daily observations nested within individuals. Analyses revealed that day-level stress was not directly related to subsequent subjective sleep indicators or to subsequent objective sleep indicators. Day-level stress was significantly associated with day-level perseverative cognition, and daily variations in perseverative cognition were significantly related to several day-level objective sleep parameters (sleep efficiency, marginally to number of awakenings, and wake after sleep onset), and to several day-level subjective sleep parameters (sleep quality, number of awakenings, wake after sleep onset). Finally, mediation analyses using path analysis suggested that, on the day level, perseverative cognition functions as a mediator between stress and several sleep parameters, namely, subjective sleep quality, objective sleep efficiency, and subjective wake after sleep onset. CONCLUSION Perseverative cognition is a promising explanatory mechanism linking day-level stress to subjective and objective measures of sleep.

The effect on sleep of being on-call: An experimental field study

The aim of this study was to: (i) gain more insight into the relationship between being on‐call and sleep and (ii) investigate the role of stress in this relationship. Data were collected by means of an experimental field study with a within‐subject design (two conditions, random order). Ninety‐six students participated during two consecutive nights: a reference night and a simulated on‐call night without an actual call. Participants were told they could be called at any time during the on‐call night. In the case of a call, participants had to perform online tasks for approximately 30 min. Self‐reported sleep quality and the extent to which participants experienced stress during the on‐call period were assessed by means of short questionnaires. Actigraphy was used to obtain objective sleep measures. Results for actigraphy data revealed no significant within‐person differences between conditions. However, participants reported longer sleep onset latencies, more awakenings and more wake after sleep onset during the on‐call night than during the reference night. They also reported more sleep problems and a lower overall sleep quality, and felt less recuperated after the on‐call night. Perceived stress moderated the relationship between being on‐call, on one hand, and the number of awakenings, wake after sleep onset, sleep problems and overall sleep quality, on the other hand. Results show that, even in the absence of an actual call, sleep during on‐call nights is of lower quality and has less restorative value – especially when being on‐call is experienced as stressful.

The state of boredom: Frustrating or depressing?

Boredom is a prevalent emotion with potential negative consequences. Previous research has associated boredom with outcomes indicating both high and low levels of arousal and activation. In the present study we propose that the situational context is an important factor that may determine whether boredom relates to high versus low arousal/activation reactions. In a correlational (N = 443) and an experimental study (N = 120) we focused on the situational factor (perceived) task autonomy, and examined whether it explains when boredom is associated with high versus low arousal affective reactions (i.e., frustration versus depressed affect). Results of both studies indicate that when task autonomy is low, state boredom relates to more frustration than when task autonomy is high. In contrast, some support (i.e., Study 1 only) was found suggesting that when task autonomy is high, state boredom relates to more depressed affect than when task autonomy is low. These findings imply that careful attention is needed for tasks that are relatively boring. In order to reduce frustration caused by such tasks, substantial autonomy should be provided, while monitoring that this does not result in increased depressed affect.

Let's have fun tonight: The role of pleasure in daily recovery from work

The present study aims to advance insight into the role of pleasure in the daily effort-recovery cycle. Specifically, using a within-individual study design, we examine the associations between the pleasure employees experience during the evening after work and their recovery state that evening and at various points in time during the next workday. We also investigate associations between employees recovery state at the end of the workday and the pleasure they experience during the subsequent evening. Multilevel analyses show that on days when employees experience higher levels of pleasure during the evening after work, they have a more favorable recovery state during that evening. Importantly, the extent to which employees experience pleasure during the evening after work is also positively related to their recovery state during the next workday. Finally, our study shows that on days when employees are in a more unfavorable recovery state at the end of the workday, they experience lower levels of pleasure during the subsequent evening after work. This study increases our insight into the role of pleasure in recovering from work and underlines the importance of engaging in pleasant activities after work.
