Psychological factors related to physical, social, and mental dimensions of the SF-36: a population-based study of middle-aged women and men

Pelvic floor physical therapy in the treatment of chronic anal fissure (PAF trial): quality of life outcome

BACKGROUND

Chronic anal fissure is one of the most common anorectal diseases and is associated with reduced quality of life. The aim of this study was to investigate the effects of pelvic floor physical therapy on quality of life in patients with chronic anal fissure using the Short-Form 36 Health Survey (RAND-36).

METHODS

Adult patients, with chronic anal fissure and concomitant pelvic floor dysfunction, such as dyssynergia and increased pelvic floor muscle tone, were recruited at the Proctos Clinic in the Netherlands, between December 2018 and July 2021 and randomly assigned to an intervention group, receiving 8 weeks of pelvic floor physical therapy or assigned to a control group receiving postponed pelvic floor physical therapy (PAF trial). Quality of life and pain ratings were outcomes of the study and were measured at 8- and 20-week follow-up.

RESULTS

One hundred patients (50 women and 50 men, median age 44.6 years [range 19-68 years]), completed the RAND-36 questionnaire and visual analog (VAS) pain scale score at admission. A significant improvement was found at 20-week follow-up in all domains of the RAND-36; physical functioning, pain, health change (p < 0.001); physical role, vitality, general health, social functioning, emotional role, mental health (p < 0.05). VAS pain was significantly reduced at 8 weeks (mean estimated difference 1.98; 95% CI 1.55-2.42, p < 0.001) and remained significant at 20-week follow-up (p < 0.001). The difference between the groups as regards change in the mean pain intensity scores at 8 weeks was 2.48 (95% CI - 3.20 to - 1.75; p < 0.001). Compared to the reference values of the general Dutch population, the patients in our study with a chronic anal fissure and pelvic floor dysfunction reported an impaired quality of life in 8 of 9 domains of the RAND-36. After treatment, significant lower scores were found in 2 out of 9 domains.

CONCLUSIONS

The results of this study provide evidence that treatment by pelvic floor physical therapy improves quality of life and reduces pain, making it an important tool in management of chronic anal fissure and concomitant pelvic floor dysfunction.

Health-related quality of life (SF-36) in back pain: a population-based study, Campinas, São Paulo State, Brazil

Our study aimed at assessing back pain impact over health-related quality of life (HRQoL). This is a cross-sectional population-based study that analyzed 1,192 adults. The dependent variables were the SF-36 scales and the main independent variables was back pain characterized by location, number of back pain region, intensity, frequency and limitations. Simple and multiple linear regression models were performed to estimate the crude and adjusted beta-coefficients (gender, age, schooling and co-morbidity conditions). Back pain prevalence were 35.4%. For HRQoL, comparing people with/without back pain, we found weak associations for the physical component (β = -3.6). However, strong associations were found for physical component (β = -12.4) when there were concomitant pain in cervical, dorsal and lumbar sites and also associations with mental health scales. Daily pain was associated with physical (β = -6.8) and mental (β = -2.7) components. Important impact on physical componente summary was found for intense/very intense pain (β = -7.9) and pain with severe limitation (β = -11.5). The impacts over HRQoL were strong when back pain was followed by (1) multiple back sites, (2) with pain in mental componente summary, (3) daily complaints, (4) very intense pain and (5) severe limitations; these results have revealed the importance to measure specific factors related to back pain.

Measuring psychosocial factors in health surveys using fewer items

The present study investigated the possibility of reducing length of psychosocial scales, while maintaining validity, using easily manageable techniques. Data were collected 2003–2004 in a Swedish general population; n = 1007, ages 45–69, 50% women. Eight psychosocial scales were reduced from 6–20 to 3–7 items maintaining Cronbach’s alpha >0.7 and correlation coefficients between full and reduced scales > 0.85. Relationships to biomarkers for inflammation, self-rated health and 8-year incidence of coronary heart disease showed no difference between full and reduced scales. It was possible, using these easily manageable methods, to reduce scale length without threatening validity for use in population surveys.

A systematic scoping review of psychosocial and psychological factors associated with patient activation

OBJECTIVE

Patient activation has been identified as an important predictor of how patients manage their own health, but little is known about its determinants. In this scoping review, we aim to address this research gap by (1) identifying literature on psychosocial/psychological factors associated with patient activation, and (2) extracting and synthesizing major results reported on that relationship.

METHODS

Using a systematic search of four electronic databases (Web of Science, PubMed, PsychInfo, CINAHL), our search algorithm combined related terms for "psychosocial factors" or "psychological factors" and "patient activation".

RESULTS

Of the 1128 records identified, we included 13 studies in this scoping review. In these, we identified 21 psychosocial/psychological factors that were significantly associated with patient activation. The four most frequently investigated factors were depression, self-efficacy, hope, and health status. Overall, the methodological quality of studies was low. The majority were cross sectional in design, and only one assessed causality.

CONCLUSIONS

Our results suggest that psychosocial/psychological factors explain variations in patient activation. However, further research is needed to identify causal relationships between psychosocial/psychological factors and patient activation.

PRACTICE IMPLICATIONS

The insights from our review could be used for designing and evaluating interventions to improve patient activation.

SF-36 predicts 13-year CHD incidence in a middle-aged Swedish general population

Purpose

To study the predictive ability of each of the eight scales of SF-36 on 13-year all-cause mortality and incident coronary heart disease (CHD) in a general middle-aged population.

Methods

The population-based, longitudinal “Life-conditions, Stress and Health” study, in 2003–2004 enrolled 1007 persons aged 45–69 years (50% female), randomly sampled from the general population in Östergötland, Sweden. Variables at baseline included the SF-36 (health-related quality of life, HRQoL) and self-reported disease. Incident CHD (morbidity and mortality) and all-cause mortality data for the study population during the first 13 years from baseline were obtained from national Swedish registries.

Results

Seven of the eight SF-36 scales predicted CHD (sex- and age-adjusted Hazard Ratios up to 2.15; p ≤ 0.05), while only the Physical Functioning scale significantly predicted all-cause mortality. Further adjustments for presence of (self-reported) disease did not, in most cases, alter these significant predictions.

Conclusion

Low SF-36 scores predict risk of CHD, also after adjustment for present disease, supporting the biopsychosocial model of health and disease. Measures of HRQoL yield important information and can add to the cardiopreventive toolbox, including primary prevention efforts, as it is such a simple and relatively inexpensive tool.

Psychosocial factors and hypertension prevalence among Ghanaians in Ghana and Ghanaian migrants in Europe: The RODAM study

Despite progress made to prevent and control hypertension, its prevalence has persisted in many countries. This study examined the associations between psychosocial factors and hypertension among Ghanaian non-migrants and migrants. Data were drawn from the Research on Obesity and Diabetes among African Migrants (RODAM) project. Findings show that among migrant women, those who experienced periods of stress at home/work had higher odds of hypertension. Among non-migrants, women with depression symptoms were more likely to be hypertensive. Furthermore, there was a positive association between negative life events and hypertension among non-migrant men. The findings highlight the importance of psychosocial factors in addressing hypertension prevalence in Ghanaian populations.

Hopelessness: Independent associations with health-related quality of life and short-term mortality after critical illness: A prospective, multicentre trial

PURPOSE

To assess the independent associations between ability to cope and hopelessness with measures of health-related quality of life (HRQoL) and their effects on mortality up to 3 years after discharge in patients who have been treated in an intensive care unit (ICU).

METHODS

A prospective, cross-sectional multicenter study of 980 patients. Ability to cope, hopelessness, and HRQoL were evaluated using validated scales. Questionnaires were sent to patients 6, 12, 24, and 36 months after discharge from ICU.

RESULTS

After adjustment, low scores for ability to cope and high scores for hopelessness were both related to poorer HRQoL for all subscales (except for coping with bodily pain). Effects were in the same range as coexisting disease for physical subscales, and stronger for social and mental subscales. High scores for hopelessness also predicted mortality up to 3 years after discharge from ICU (p<0.001).

CONCLUSIONS

The psychological factors ability to cope and hopelessness both strongly affected HRQoL after ICU care, and this effect was stronger than the effects of coexisting disease. Hopelessness also predicted mortality after critical illness. Awareness of the psychological state of patients after a stay in ICU is important to identify which of them are at risk.

Psychological factors influence the overlap syndrome in functional gastrointestinal disorders (FGIDs) among middle-aged women in South Korea

This study investigated the psychological factors related to the overlap syndrome, i.e., multiple gastrointestinal conditions that are part of functional gastrointestinal disorders (FGIDs) in the same individual and potentially related to quality of life (QOL) among women aged 45-60 years (n = 627) in South Korea. The study was undertaken between July 2014 and March 2015. Depressive and anxiety symptoms were ascertained using the Center for Epidemiologic Studies Depression scale (CES-D) and the Beck Anxiety Inventory (BAI), respectively. Negative cognition and the cognitive triad were identified using the Automatic Thoughts Questionnaire-Negative (ATQ-N) and the Cognitive Triad Inventory (CTI), respectively. Resilience and QOL were assessed using the Connor-Davidson Resilience Scale (CD-RISC) and World Health Organization Quality of Life scale abbreviated version (WHOQOL-BREF). Women with the overlap syndrome had the highest CES-D (mean = 16.66 ± 11.79, p < .001), BAI (mean = 17.46 ± 12.67, p < .001), and ATQ-N scores (mean = 53.61 ± 20.88, p < .001), followed by women with gastrointestinal disorders but without the overlap syndrome and healthy controls. Healthy controls had the highest WHOQOL-BREF score (mean = 77.69 ± 12.53, p < .001). After stepwise selection, the final model explained 61.8 percent of the variance in QOL. Thus, depressive symptoms, anxiety, negative cognition, cognitive triad, and resilience were significantly related to QOL in women with the overlap syndrome.

Patient perceptions of physical health and bipolar symptoms: The intersection of mental and physical health

BACKGROUND

Affective symptoms and medical comorbidities have a negative impact on the course of bipolar disorder. The aim of this analysis was to examine how the perceptions of physical health and functioning in individuals with bipolar disorder relate to their mood symptoms.

METHODS

We analyzed longitudinal data from the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) on the physical subscales of the Short Form Health Survey (SF-36) (physical functioning, role limitations due to physical problems, bodily pain, and general health).

RESULTS

Participants' perception of their overall physical health predicted severity of mania/hypomania, depression, and life satisfaction at concurrent and future visits. Perceptions of role limitations due to physical health problems predicted depressive symptoms and poor life satisfaction. Worse bodily pain predicted symptoms of mania/hypomania. Reports of specific or concrete physical limitations in daily life showed no associations with psychiatric symptoms at concurrent assessments, but did predict worse course of illness one year later. SF-36 scores showed significant, but small associations with the presence of medical comorbidities.

LIMITATIONS

Perceptions of physical health and quality of life were self-report, potentially lending themselves to transient negative biases, particularly among depressed participants. Additionally, the SF-36 was selected as a generic, widely used measure; as a result, it was not specific to the illness burden of bipolar disorder.

CONCLUSION

Overall, broad perceptions of poor physical health were associated with worse course of illness over the 24 months of the study. Though further research is warranted, changes in subjective physical health related quality of life, even independent of objective health changes, may offer important insight into global wellbeing and be targets of psychotherapy treatment.

The joint subclinical elevation of CRP and IL-6 is associated with lower health-related quality of life in comparison with no elevation or elevation of only one of the biomarkers

Background

Measures of health-related quality of life (HRQoL), like the Short Form (SF)-36, have been suggested to correlate with inflammatory biomarkers. It is, however, unclear whether a joint measure of two inflammatory biomarkers would bring additional information in comparison with evaluation of one inflammatory biomarker.

Objective

To evaluate associations between SF-36 and low-grade inflammation in a Swedish population, with emphasis on a combined measure of C-reactive protein (CRP) and interleukin-6 (IL-6) as a proxy for low-grade inflammation.

Methods

In a randomly selected sample of a middle-aged Swedish general population (n = 905; aged 45–69 years, 50 % women), relations between SF-36 parameters and the biomarkers were tested. Regression and correlation analyses were adjusted for sex, age, presence of disease, lifestyle, and psychological factors.

Results

After adjustment for sex and age, HRQoL was significantly lower in the group with a joint elevation of CRP and IL-6 in comparison with either the group with no elevation or the groups showing elevation of one of the two biomarkers. Also after full adjustments, the combined measure of elevated CRP and IL-6, with few exceptions, was associated with significantly lower HRQoL in comparison with elevations in one of them, difference ranging from 4 (Mental Health scale) to 18 scale steps (Role-Physical scale).

Conclusion

This study confirms that there is a relationship between HRQoL and low-grade inflammation. In particular, SF-36 scores are significantly lower in a group with joint elevation of IL-6 and CRP, in comparison with elevation of either one of them.

Influence of self-reported chronic rhinosinusitis on health-related quality of life: a population-based survey

Chronic rhinosinusitis (CRS) is a frequently occurring chronic respiratory disease. There is evidence that effective treatment of CRS can improve patients’ quality of life, but the data regarding the extent to which CRS impairs patients’ quality of life (QoL) is sparse. This study aimed to evaluate the effect of self-reported CRS on health-related QoL and to determine whether the influence was associated with gender, age and socio-economic status. A four-stage random sampling method was used to select the participants from the general population in Guangzhou, China. All participants were interviewed face-to-face at their homes using a standardized questionnaire. The health-related QoL of each participant was assessed using the SF-36 Health Survey. The scores of the SF-36 after adjusting for gender, age, socioeconomic conditions, smoking and some important comorbid conditions were compared between the CRS group and the non-CRS group using analysis of covariance. A multiple linear regression model with interaction terms was established to determine whether CRS affected QoL to the same degree across the different subpopulations. Among a total of 1,411 participants aged at least 15 years, 118 persons (8.4%) had self-reported CRS. Subjects with CRS had an increased prevalence of allergic rhinitis, chronic obstructive pulmonary disease and gout than subjects without CRS. The CRS group had lower scores in all eight domains and the physical and mental component summary than those without CRS (P<0.05), and the greatest differences were in role emotional function (RE), general health (GH) and role physical function (RP). The impairments of the CRS participants in RE and RP were greater among the females than the males. Moreover, physical domains were affected to greater degrees among the elderly and those with high-level education. In conclusion, CRS is a common chronic disorder. Persons with self-reported CRS perceived themselves as having impaired QoL in both the physical and mental domains. These findings shed new light on the health burden of CRS and should be taken into account by clinicians involved in the care of CRS patients.

Sense of coherence and pain experience in older age

BACKGROUND

We investigate to what extent pain in older individuals is predicted by on the one hand chronic morbidity as a resistance deficit, and on the other hand psychological resistance resources and the sense of coherence. For the first time, we tested the salutogenic hypothesis that the sense of coherence mediates the relationship between resources/deficits and pain.

METHODS

In our questionnaire study, we assessed selected psychological resistance resources (self-esteem, generalized self-efficacy, optimism, and social support), the number of self-reported medical diagnoses of chronic illness, the sense of coherence, and pain (SF-36 Bodily Pain subscale) in a sample of 387 older persons (at the mean age of 73.8 years).

RESULTS

Using hierarchical regression, we found that morbidity and sense of coherence were the only significant predictors of pain, with morbidity showing the strongest effect. Using path analysis, the sense of coherence was a mediator of the relationship between resistance resources/deficits and pain.

CONCLUSIONS

With respect to our analytical model, in which pain experience was the criterion variable, morbidity and the sense of coherence are important predictors of pain. Moreover, we found evidence for the salutogenic idea that the sense of coherence represents a mediator variable as it pools resistance/deficits influences on pain. We recommend a prospective design to explore these assumed causal chains in future research.

Association between sense of coherence and health-related quality of life among primary care patients with chronic musculoskeletal pain

BACKGROUND

Sense of Coherence (SOC) is a measure of an individual's capacity to use various coping mechanisms and resources when faced with a stressor. Chronic pain is one of the most prevalent and disabling conditions in clinical practice. This study examines the extent to which a strong SOC is associated with less pain and better health related quality of life (HRQoL) among patients with chronic pain.

METHODS

We analyzed data from the Stepped Care to Optimize Pain care Effectiveness (SCOPE) trial which enrolled 250 patients with persistent (3 months or longer) musculoskeletal pain who were receiving care in an United States Department of Veterans Affairs (VA) primary care clinic. The abbreviated three-item SOC scale was used to measure personal coping capability. Participants were categorized into Strong SOC (score 0-1) and Weak SOC (score 2-6). The Brief Pain Inventory (BPI) was used to assess the severity and disability associated with pain. Additionally, pain self-efficacy (ASES) and catastrophizing (CSQ) were assessed. HRQoL was assessed with the 36-item Short-Form Health Survey (SF-36) social functioning, vitality, and general health subscales. Multiple linear regression models were performed to examine whether SOC was independently associated with pain-specific and HRQoL outcomes, after adjusting for sociodemographic and socioeconomic characteristics, medical comorbidities and major depression.

RESULTS

Of the 250 study patients, 61% had a strong SOC whereas 39% had a weak SOC. Multivariable linear regression analysis showed that a strong SOC was significantly associated with better general health, vitality, social functioning and pain self-efficacy as well as less pain catastrophizing. These significant findings were partially attenuated, but remained statistically significant, after controlling for major depression. SOC was not significantly associated with pain severity or pain disability.

CONCLUSIONS

A strong SOC is associated with better HRQoL and self-efficacy as well as less catastrophizing in patients with chronic pain. SOC may be an important coping mechanism (strategy) for patients with chronic musculoskeletal pain.
