Perception de la tension au travail (job strain) en milieu hospitalier à Pointe-Noire, Congo-Brazzaville / Perception of job strain in the hospital environment at Pointe-Noire, Congo-Brazzaville

Objectif : Evaluer la situation de job strain et les manifestations psychosomatiques ressenties par les personnels soignants des hôpitaux de Pointe-Noire. Méthodologie : L'étude était une enquête transversale analytique. Un auto-questionnaire monté selon le modèle « demande-contrôle-soutien ¼ de KARASEK, avait été utilisé pour recueillir de manière anonyme des données sociodémographiques, des informations relatives à l'état de santé, à leur poste de travail et d'identifier des facteurs de risques psychosociaux. Résultats : Sur l'ensemble des cent cinquante (150) soignants retenus, 47,02% présentaient une faible latitude décisionnelle contre 52,98% avec une forte latitude. La forte demande psychologique était perçue par 50,33% des soignants contre 49,67% avec une faible demande. La situation de job strain était retrouvée chez 26,67% des soignants. Les services des urgences et de médecine étaient les plus exposés avec respectivement 25% et 20% du personnel en situation de job strain. Une faible ancienneté au travail prédisposait à une perception de job strain plus élevée. Les médecins spécialistes et les infirmiers représentaient les catégories professionnelles les plus tendus avec respectivement 42,86% et 30,23% des individus concernés. Un lien statistique était retrouvé entre d'une part le job strain et d'autre part les troubles musculosquelettiques et l'auto-estimation de l'impact du travail sur la santé. Conclusion : Les risques psychosociaux notamment le stress sont une préoccupation réelle dans les établissements de soins et cette enquête a permis de noter qu'ils pourraient avoir des conséquences sur la santé des soignants à Pointe-Noire.

Objective: To assess the job strain situation and the psychosomatic manifestations felt by the health care worker of the Pointe-Noire hospitals. Methodology: It was an analytical cross-sectional survey. A self-questionnaire set up according to the KARASEK "demand-control-support" model had been used to anonymously collect sociodemographic data, information on their health situation, at their workplace and identify psychosocial risk factors. Results: of one hundred and fifty (150) caregivers considered, 47.02% had low decision latitude versus 52.98% with high latitude. The high psychological demand was felt by 50.33% of the medics versus 49.67% with a low demand. The job strain situation was found among 26.67% of medics. Emergency and medical departments were the most exposed with 25% and 20% of staff in a job-strain situation respectively. Low job seniority predisposed to a higher feeling of job-strain. Specialist doctors and nurses represented the most strained professional categories with 42.86% and 30.23% of the individuals concerned respectively. A statistical relation was found between job strain on the one hand and musculoskeletal trouble and self-estimation of the impact of work on health on the other hand. Conclusion: Psychosocial risks, particularly stress, are a real concern in health institutions and this survey note that there could be impact on medics' health in Pointe-Noire.

Occupational stress and job dissatisfaction with health work

Abstract Objective: The purpose of this study is to evaluate the association between psychosocial aspects at work and dissatisfaction among health workers in five cities in Bahia, Brazil. Methods: The evaluation was based on different models proposed to measuring occupational stress and possible combinations between them: demand-control model (DCM) and effort-reward imbalance (ERI). We conducted a cross-sectional epidemiological study including 3084 health workers. The analysis considered the association between partial/full/partial (combined) occupational stress models (the variable "exposure") and job dissatisfaction (the variable "outcome"). Results: Dissatisfaction rate was 26%. Full DCM and ERI models were better than partial ones to investigate job dissatisfaction. After adjustments, the combined models presented more robust measures of prevalence ratio than models evaluated separately (PR 2.93; CI 2.26-3.80). Conclusions: The combination of models has shown greater capacity to identify situations of job dissatisfaction and provided more potential information to support actions for workers' health. (AU)

Domestic work stress and self-rated psychological health among women: a cross-sectional study in Japan

BACKGROUND@#Despite the huge burden of domestic work on women in Japan, its effects on their health have been poorly investigated. We aimed to assess the association between domestic work stress and self-rated psychological health among women.@*METHODS@#We conducted a cross-sectional survey using an online social research panel in February 2018. Participants were 2,000 women with paid work (the "workers" group) and 1,000 women without paid work (the "homemakers" group), aged between 25 and 59 years old and living with a partner. Self-rated psychological health (Mental Health and Vitality scales of the Japanese SF-36), occupational and domestic work stress (the Brief Job Stress Questionnaire), the 10-item Work-Family Conflict Scale, and sociodemographic factors were assessed.@*RESULTS@#The workers had lower domestic job control and higher support from a partner and their parents than the homemakers (p < 0.001), whereas domestic job demand and psychological health were similar between the groups. After adjustment for the covariates using multiple linear regression models, better psychological health was significantly associated with lower domestic job demand, higher domestic job control, and having a young child in both groups. In addition, work-family conflicts and occupational job stress among the workers and caregiving among the homemakers showed negative associations with psychological health.@*CONCLUSION@#Self-rated psychological health in women was associated with domestic work stress regardless of employment status. To promote women's health, we need to take into account the effects of domestic work, work-family conflicts, and social support from families, as well as occupational factors.

A Longitudinal Investigation of the Moderating Effect of Social Support on Job Strain Developing Non-Specific Neck Pain in Office Workers

PURPOSE: This study examined the interactions between the job strain and social support in the workplace on the development of work-related neck pain in office workers. METHODS: The participants included 62 office workers without neck pain over the last twelve months. A battery of measures evaluating the potential workplace risk factors in office settings were conducted at the baseline, and at the 12 month incidence of work-related neck pain was reported via monthly questionnaires. Survival analysis evaluated the interaction effect between job strain and social support on the development of work-related neck pain. RESULTS: The incidence of work-related neck pain was 1.91 (95% CI: 1.06 – 3.45) per 100 person months. The interaction effect between job strain and social support found that job strain may increase the risk of developing new work-related neck pain when lower social support existed in the workplace. On the other hand, the adverse effects of job strain on the development of neck pain were not significant when workers had higher social support from their colleagues and supervisors. CONCLUSION: An investigation of the moderating effects of risk factors on neck pain might reveal the unexplained relationship between the risk factors for the development of neck pain in office workers. Therefore, the interest in prevention plans and treatments should involve a comprehensive understanding of the risk factors at workplace.

A case of extensor pollicis longus (EPL) tendon rupture in an automotive assembly line worker: an ergonomic evaluation through job strain index (JSI) and musculoskeletal risk factor survey

BACKGROUND: We report a case of extensor pollicis longus (EPL) tendon rupture caused by repetitive motions and awkward posture on hand and wrist joints. CASE PRESENTATION: A 47-year-old right-handed man who worked for 15 years in an assembly line at an automotive manufacturing company has been diagnosed with a complete tear of right EPL tendon. We investigated the patient's occupational history in detail and evaluated the tasks ergonomically through musculoskeletal risk factors survey and job strain index (JSI) using the 22 task-related videos recorded by the patient. Three out of the 12 tasks (25%) were identified as high-risk work on the hand and wrist in the musculoskeletal risk factors survey in 2016. Among the 22 tasks analyzed by JSI, 11 tasks (50%) were evaluated as probably hazardous. In addition, he used localized vibration tools in 19 (86.4%) out of 22 tasks. CONCLUSION: We concluded the patient's disease was probably caused by repetitive motion and improper posture of the hand and wrist, and the hand-arm vibration is a possible cause as well.

Working Conditions, Job Strain, and Traffic Safety among Three Groups of Public Transport Drivers

BACKGROUND: Working conditions and psychosocial work factors have acquired an important role explaining the well-being and performance of professional drivers, including those working in the field of public transport. This study aimed to examine the association between job strain and the operational performance of public transport drivers and to compare the expositions with psychosocial risk at work of three different types of transport workers: taxi drivers, city bus drivers, and interurban bus drivers. METHOD: A sample of 780 professional drivers was drawn from three transport companies in Bogota (Colombia). The participants answered the Job Content Questionnaire and a set of sociodemographic and driving performance questions, including age, professional driving experience, work schedules, and accidents and penalties suffered in the last 2 years. RESULTS: Analyses showed significant associations between measures of socio-labor variables and key performance indicators such road traffic accidents and penalties. Furthermore, multiple linear regression analysis contributed to explain significantly suffered accidents from key variables of the Job Demand-Control model, essentially from job strain. In addition, throughout post-hoc analyses, significant differences were found in terms of perceived social support, job strain, and job insecurity. CONCLUSION: Work stress is an issue that compromises the safety of professional drivers. This research provides evidence supporting a significant effect of job strain on the professional driver's performance. Moreover, the statistically significant differences between taxi drivers, city bus drivers, and interurban bus drivers in their expositions to work-related stress suggest the need for tailored occupational safety interventions on each occupational group.

Interaction between demand-control and social support in the occurrence of common mental disorders / Interação entre demanda-controle e apoio social na ocorrência de transtornos mentais comuns

ABSTRACT OBJECTIVE To analyze the interaction between the psychosocial aspects of work and the occurrence of common mental disorders among health workers. METHODS This is a cross-sectional study conducted with a representative sample of workers of the primary health care of five municipalities of the State of Bahia, Brazil, in 2012. The variable of outcome were the common mental disorders evaluated by the SRQ-20, and the variables of exposure were high demand (high psychological demand and low control over the work) and low social support in the workplace. Interaction was checked by the deviation of the additivity of the effects for the factors studied from the calculation of excess risk from interaction, proportion of cases attributed to interaction, and the synergy index. RESULTS The global prevalence of common mental disorders was 21%. The group of combined exposure has shown higher magnitude (high demand and low social support), reaching 28% when compared to the 17% in the situation of no exposure (low demand and high social support). CONCLUSIONS The results strengthen the hypothesis of interaction between the factors investigated, directing to the synergy of the effects.

RESUMO OBJETIVO Analisar a interação entre aspectos psicossociais do trabalho e a ocorrência de transtornos mentais comuns entre trabalhadores da saúde. MÉTODOS Estudo transversal conduzido em amostra representativa de trabalhadores da atenção básica de cinco municípios da Bahia em 2012. As variáveis desfecho foram os transtornos mentais comuns avaliados pelo SRQ-20, as de exposição foram a alta exigência (alta demanda psicológica e baixo controle sobre o próprio trabalho) e o baixo apoio social no trabalho. A interação foi verificada pelo afastamento da aditividade dos efeitos para fatores estudados a partir do cálculo do excesso de risco devido à interação, proporção de casos atribuída à interação e índice de sinergia. RESULTADOS A prevalência global de transtornos mentais comuns foi de 21%. Apresentou maior magnitude no grupo de exposição combinada (alta exigência e baixo apoio social), chegando a 28% quando comparada a 17% na situação de nenhuma exposição (baixa exigência e alto apoio social). CONCLUSÕES Os resultados fortalecem a hipótese de interação entre os fatores investigados, com direção para a sinergia dos efeitos.

Estresse no trabalho e hipertensão arterial em profissionais de enfermagem da rede municipal de saúde de Belo Horizonte, Minas Gerais, Brasil / Job strain and arterial hypertension in nursing professionals from the municipal healthcare network in Belo Horizonte, Minas Gerais, Brazil

Resumo Objetivo: analisar a associação entre estresse no trabalho e hipertensão arterial (HA). Método: estudo transversal com amostra probabilística de 273 profissionais de enfermagem da rede municipal de saúde de Belo Horizonte, Minas Gerais, Brasil, desenvolvido entre setembro de 2008 e janeiro de 2009. O estresse no trabalho foi mensurado com o modelo de demanda-controle e a hipertensão arterial por meio do autorrelato de diagnóstico médico da doença ou uso de medicação anti-hipertensiva. Razões de prevalência (RP) de HA e seus respectivos intervalos de confiança de 95% (IC 95%) foram ajustados pela técnica de regressão multivariada de Poisson. Resultados: dos profissionais estudados, 42,1% eram enfermeiros e 57,8%, técnicos ou auxiliares de enfermagem. A HA foi diagnosticada em 16,9%. Sexo feminino (RP = 0,56), avançar da idade (p de tendência linear < 0,001), renda familiar de 4 ou mais salários mínimos (RP = 0,39) e o estresse no trabalho (RP = 2,53) permaneceram independentemente associadas à HA após o ajuste multivariado dos dados. Conclusões: o estresse no trabalho está associado à HA em profissionais de enfermagem da rede municipal de saúde de Belo Horizonte. Este achado deve ser levado em consideração na formulação de políticas públicas que envolvem a promoção da saúde desses trabalhadores.

Abstract Objective: to assess the association between job strain and arterial hypertension (AH). Method: cross-sectional study with random sample of 273 nursing professionals from the municipal healthcare network in Belo Horizonte, Minas Gerais, Brazil, conducted between September 2008 and January 2009. Job strain was measured using the demand-control model and hypertension by self-report medical diagnosis of the disease or use of antihypertensive medication. Prevalence ratios (PR) of AH and their respective 95% confidence intervals (95% CI) were adjusted by Poisson multivariate regression. Results: among the professionals studied, 42.1% were nurses and 57.8% were nursing technicians or assistants. The AH was diagnosed in 16.9%. Female sex (PR = 0.56), increasing age (p of linear trend < 0.001), household income of 4 or more minimum wages (PR = 0.39) and job strain (PR = 2.53) were independently associated to AH after the multivariate adjustment. Conclusions: job strain is associated with AH among nursing professionals from the municipal healthcare network in Belo Horizonte. This finding must be considered in the formulation of public policies involving the health promotion of these workers.

Effect of maternal job strain during pregnancy on infant neurodevelopment by gender at 6 and 12 months: Mothers and Children's Environmental Health (MOCEH) study

OBJECTIVES: Limited evidence is available regarding the association between prenatal job strain and infant neurodevelopment. Most studies used stress indicators other than job strain to explain the relationship between prenatal maternal stress and child development. The objective of this study was to investigate the association between maternal job strain during pregnancy and neurodevelopment in infancy. METHODS: Mothers and Children's Environmental Health (MOCEH) study, an on-going prospective birth cohort study, has been conducted in South Korea since 2006. Job strain during pregnancy was measured using Korean version of Job Content Questionnaire (JCQ). Infant neurodevelopment was assessed using Korean Bayley Scale of Infant Development II (K-BSID-II) at 6 and 12 months of age. A total of 343 mother-child pairs that completed JCQ and K-BSID-II more than once were included. Mental Developmental Index (MDI) and Psychomotor Developmental Index (PDI) defined in the K-BSID-II were used as outcome variables. RESULTS: Compared to infants from mothers with low job strain, significant (p < 0.05) decreases in PDI were found in infants from mothers with active and passive job at 6 months of age. After stratification by infant sex, boys in the high strain group had a lower MDI score than boys in the low job strain group at 12 months. On the other hand, girls in the high strain and active groups had higher MDI scores than girls in the low job strain group at 12 months. PDI at 12 months also showed different results by sex. Boys in the high strain and passive job groups had lower PDI scores than boys in the low job strain group. However, such difference was not observed in girls. CONCLUSIONS: The findings of this study suggest that prenatal job strain affects infant neurodevelopment in a gender-dependent manner.

Reliability and Validity of the Greek Version of the Job Content Questionnaire in Greek Health Care Workers

BACKGROUND: The Job Content Questionnaire (JCQ), which is based on the DemandeControleSupport model, is designed to measure the psychosocial characteristics of the respondent's work, and has been identified to predict health and psychological outcomes. The purpose of this study was to investigate the psychometric properties of this instrument and the subsequent adaptation of its scales to the population of Greek health workers. METHODS: The Greek version of the JCQ was developed by using forward- and back-translation in accordance with the JCQ policy. The reliability and validity of the measure were investigated in a sample of health workers working in a hospital in Athens, Greece. The internal consistency of the scales was examined based on Cronbach alpha coefficients, and the validity was evaluated subjecting the items of the three main scales of the JCQ (decision latitude, psychological job demands, and social support) to exploratory and confirmatory factor analysis. RESULTS: The reliability of the scales was found to be acceptable for all the scales, except for the skill discretion subscale. Confirmatory factor analysis confirmed a slightly modified version of the original construct including several items to more than one factor. CONCLUSION: Our findings suggest that the Greek JCQ is reliable and valid for investigating psychosocial job characteristics among Greek health workers.

Prevalence and Contributing Factors of Job Strain among Crane Operators in a Port Container Terminal in Malaysia

The information on job strain among crane operators in Malaysia is lacking. The aim of this study was to determine the prevalence and contributing factors of job strain among crane operators working in port container terminals. A cross sectional study was carried out at a port container terminal in Malaysia. Data was collected using validated self-administered questionnaires, which consisted of the Job Content Questionnaire (JCQ), and the Depression, Anxiety, and Stress Scale (DASS-21). All crane operators in the selected terminal participated in the study. Data was analyzed using SSPS version 19. Two-hundredand-forty crane operators participated in the study.. The prevalence of job strain determined from the JCQ was 43.8%. Job strain was significantly associated with psychological job demand, decision latitude, anxiety, physical isometric loads and muscle ache. The prevalence of job strain in this study was high. There is an urgent need to recognize the existence of this problem among crane operators by their respective management. Implementation of comprehensive stress management programs are recommended to reduce job strain among these workers. Keywords:I

Relationship between Psychosocial Risk Factors and Work-Related Musculoskeletal Disorders among Public Hospital Nurses in Malaysia

OBJECTIVE: This study examined the relationships between psychosocial work factors and risk of WRMSDs among public hospital nurses in the Klang Valley, Malaysia. METHODS: We conducted a cross-sectional study among 660 public hospital nurses. A self-administered questionnaire was used to collect data on the occurrence of WRMSDs according to body regions, socio-demographic profiles, occupational information and psychosocial risk factors. 468 questionnaires were returned (response rate of 71%), and 376 questionnaires qualified for subsequent analysis. Univariate analyses were applied to test for mean and categorical differences across the WRMSDs; multiple logistic regression was applied to predict WRMSDs based on the Job Strain Model's psychosocial risk factors. RESULTS: Over two thirds of the sample of nurses experienced discomfort or pain in at least one site of the musculoskeletal system within the last year. The neck was the most prevalent site (48.94%), followed by the feet (47.20%), the upper back (40.69%) and the lower back (35.28%). More than 50% of the nurses complained of having discomfort in region one (neck, shoulders and upperback) and region four (hips, knees, ankles, and feet). The results also revealed that psychological job demands, job strain and iso-strain ratio demonstrated statistically significant mean differences (p < 0.05) between nurses with and without WRMSDs. According to univariate logistic regression, all psychosocial risk factors illustrated significant association with the occurrence of WRMSDs in various regions of the body (OR: 1.52-2.14). Multiple logistic regression showed all psychosocial risk factors were significantly associated with WRMSDs across body regions (OR: 1.03-1.19) except for region 1 (neck, shoulders and upper back) and region 4 (hips, knees, ankles, and feet). All demographic variables except for years of employment were statistically and significantly associated with WRMSDs (p < 0.05). CONCLUSIONS: The findings indicated the high prevalence of WRMSDs in many body regions, and the risks of developing WRMSDs according to the various body regions were associated with important psychosocial risk factors based on the job strain model. These findings have implications for the management of WRMSDs among public hospital nurses in the Klang Valley, Malaysia.

Psychosocial stressors in inter-human relationships and health at each life stage: A review

Currently, psychosocial stressors' impacts on health are increasing. Among these stressors, this review focused on inter-human relationships. Since social supports could be protective against ill health, consequences contributing to psychosocial stressors are discussed here in relation to social supports for each stage of childhood, adulthood and elderly status.For childhood, parental divorce/isolation, and child abuse/neglect appeared to be determinants of healthy development at either the initial or later stages. According to prospective studies, such stressors, especially those occurring until around 3 years of age, were associated with later adverse life quality in adulthood. Therefore, nationwide preventive strategies were developed in each country to monitor protective social programs.For adulthood, job strain was focused on Karasek's job strain model, effort-reward imbalance, employment grade and working hours. These psychosocial stressors were shown to affect not only the physical health but also the mental health of working people. These days, since Karoshi and even suicide related to excessive workloads are taking a toll on workplace organization, stress-coping abilities such as a sense of coherence were introduced from the individual-social interaction aspect.For elderly status, retirement, caring for the elderly, and spouse bereavement were discussed as psychosocial stressors. Some evidence indicates that these stressors could be determiants of health. Finally, social supports have been demonstrated to promote health and protect the elderly against diseases and death.

Occupational Distribution of Job Stress in Korea / 대한산업의학회지

OBJECTIVES: Although there is increasing concern about job stress, no published reports have addressed the basic characteristics of job stress (i.e. on various job stress domains), according to the Korean Standard of Job Categories. Therefore, this study was conducted to present epidemiologic data of common Korean workers on job stress domains, by using the self-reported Karasek's Job Content Questionnaire(JCQ.) METHODS: Data were gathered from many workers at various industries for 2 years, as a part of the workers'periodic health examinations, in Kyong-Gi and Kyong-Nam provinces, Korea. RESULTS: The total respondents were 1,866, male 1,658(88.9%) and female 208(11.1%), from 117 companies. The mean age was 35.05 years old, 1,315(70.4%) were married, 1,578(84.5%) were graduated from high school or above, and 380(20.4%) were managers at workplace. The mean scores of decision latitude, psychological job demand, social support, and job insecurity were 62.56(std 8.28, median 62), 31.45(std 3.83, median 32), 22.49(std 2.58, median 23) and 6.16(std 1.90, median 6), respectively. Construction workers belonged to the high strain group, and administrative managers and computer related experts belonged to the active group. CONCLUSIONS: To more precisely evaluate job stress according to job categories, data could be gathered from a larger sample and detailed job categories should be adopted. Such a study would form an important foundation for research into job stress in Korea.

Combined effects of job strain, shift work and life style on the prevalence of sleep problems in middle aged men

BACKGROUND: There are a few studies on the effects of job strain on the prevalence of sleep problems in the foreign countries. In Korea, it has not been studied till now. In this article, the combined effects of job strain, shift work and some life style on the prevalence of sleep proplems were studied among workers in middle aged men. METHODS: 998 cases were chosen from 1109 men who visited health screening center from October to November, 1999. Sleep problems were categorized to insomnia, sleep deprivation, daytime sleepiness and snoring on the base of result of factor analysis of 11 questions. Job strain was measured by 11 questions which developed by Karasek and Theorell. All data set were analyzed using Chi square test and multiple logistic regression analysis. RESULTS: The 4 sleep proplems were analyzed by multiple logistic regression analysis in relation to job strain, shift work, occupation, obesity, sedentary life style, smoking, drinking. Insomnia was increased significantly from highest job strain group(Odds ratio (OR:2.02)) and non exercise group(OR:2.05). In these groups, daytime sleepiness was increased significantly(OR=1.92 in the highest job strain group, OR=1.72 in non exercise group). Sleep deprivation was increased in the highest job strain group(OR=2.18), managers & clerks(OR:1.67) and non exercise group(OR:1.78). Snoring was increased from BMI(Body mass index)> OR =25(OR=1.77), BMI> OR =27(OR=2.80) and non exercise group(OR:1.87). CONCLUSION: In the highest job strain group, insomnia, sleep deprivation and daytime sleepiness was increased significantly. And sedentary life style increased all sleep problems.

Study on Perceived Occupational Psychosocial Stress and Work-related Musculoskeletal Disorders among VDT Works / 대한산업의학회지

It has been hypothesized that jobs that have both high psychological demands and low decision latitude ('job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome (MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model (16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects (n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-strain group, and OR of musculoskeletal disorder was 2.446 (95% C.I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

Effect of Economic Depression on Psychosocial Distress of Industrial Workers / 대한산업의학회지

This study was carried out to assess the effect of economic depression on psychosocial distress, and to assess the relationship between differences of psychosocial distress and job characteristics (job strain), and to find out the effect of social support on psychosocial distress. We measured job characteristics(job demand, job control), and social support(coworker support, supervisor supports) at work by a self-administered questionnaire. Psychosocial distress was measured by PWI(Psychosocial Well-being Index), a 45-item self-administered instrument. Among the 152 respondents, the prevalence of high job strain was 27% (41 persons). The Odds ratio of high job strain was 3.11 (95% CI; 2.12~4.11), and those of passive group and active group were 2.01(95% CI; 0.83~2.76) and 1.80(95% CI; 0.83~2.76), respectively. Our results supported the association between psychosocial distress and job strain. The odds ratio of high strain isolates group (high strain group+low social support) was 3.59 (95% CI; 2.05~5.13), but the odds ratio of high strain collective group was 1.32 (95% CI; 0.23~2.41). Social support at work was modifying factor of the association between psychosocial distress and job strain. Therefore we reviewed the evidence that economic depression was associated with psychosocial distress in this study, and that the strength of the social support was important in maintain health.

Association between Job characteristics and Psychosocial Distress of Industrial Workers / 예방의학회지

This study was carried out to assess the relationship between job characteristics(job strain) and psychosocial distress, and to find out the effect of social support on psychosocial distress. The study design was cross-sectional, and included 1,211 industrial workers in middle-sized city. A self-administered questionnaire measured job characteristics(jod demand, job control), and social support(coworker support, supervisor support) at work. Psychosocial distress was measured using PWI(Psychosocial Well-being Index), a 45-item self-administered instrument. Among the 1,211 respondents, the prevalence of psychosocial distress was 24.8%. High job strain (high job demand + low job control) was present in 8% of the subjects. The crude odds ratio of high job strain was 4.76 (95% CI : 2.60-8.74), and those of active group and passive group were 3.81(95% CI : 1.82-3.95) and 2.64(95% CI : 1.77-3.94), respectively. The odds ratios of each group adjusted for sex, age, support, and religion were still significant. Our results supported the association between job strain and psychosocial distress. Social support at work, although significantly associated with psychosocial distress, did not modify the association between job strain and psychosocial distress.
