Cancer survivors' experiences of a physical activity program in primary care: a qualitative study.

PURPOSE: This study aimed to gain insight into the experiences of, and reasons for, cancer survivors participating in a primary care PA program. METHODS: We interviewed 17 patients from 11 Dutch GP practices. Patients were selected by purposive sampling based on their general practice, gender, educational level, motivation for PA, and change in PA. Interviews were audio recorded, transcribed verbatim, and pseudonymized for inductive thematic analysis. RESULTS: Three domains were identified with five themes: institutional domain: GP practice; program-specific domain: content sessions and PA, and activity tracker and goal setting; individual domain: experienced benefits, and personalized care needs. Participants valued the PA program because it was offered close to home, without additional costs, and by a trusted practice nurse familiar with the patients' medical background. Activity tracker use and goal setting motivated many participants but also led to demotivation and feelings of failure in others. Reported benefits included behavior change and favorable health outcomes. Many patients expressed the need to personalize psychological support and the program's timing. CONCLUSIONS: Access to a PA program in a primary care setting is valued for its accessibility and experienced health benefits, but also seems to meet an unmet need for support in picking up life during cancer recovery. IMPLICATIONS FOR CANCER SURVIVORS: Primary care is important for continued care of cancer survivors. An accessible PA program in this setting may fulfil a need for not only lifestyle support but also continuing life after cancer treatment.

The effects of a moderate physical activity intervention on physical fitness and cognition in healthy elderly with low levels of physical activity: a randomized controlled trial.

BACKGROUND: Increasing physical activity is one of the most promising and challenging interventions to delay or prevent cognitive decline and dementia. METHODS: We conducted a randomized controlled trial to assess the effects of a physical activity intervention, aimed at increasing step count, in elderly with low levels of physical activity on measures of strength, balance, aerobic capacity, and cognition. Participants were assigned to 9 months of exercise counseling or active control. RESULTS: The intention-to-treat analyses show that the intervention, compared to control, increases the level of physical activity, but has no significant effect on physical fitness and cognition. Those who increased their physical activity with 35% or more show significant improvements in aerobic capacity, gait speed, verbal memory, executive functioning, and global cognition, compared to those who did not achieve a 35% increase. LIMITATIONS: The number of participants that achieved the intended improvement was lower than expected. CONCLUSION: Responder analyses suggest an improvement of physical fitness and cognition in those who achieved an increase in physical activity of at least 35%. TRIAL REGISTRATION: The trial protocol is registered at the Dutch Trial Register NL5675, August 1, 2016.

Implementation and evaluation of a physical activity counselling programme in primary care among cancer survivors: SoDA study protocol.

INTRODUCTION: Physical activity (PA) favourably affects various health outcomes in cancer survivors, but little is known about how to implement a PA programme in primary care. We therefore aim to implement and evaluate such a programme for cancer survivors in general practice. METHODS AND ANALYSES: The Stimulation of Daily Activity study is an implementation study with a single-arm longitudinal design in 15 Dutch general practices. Patients aged ≥18 years who finished cancer treatment more than 6 months ago will be eligible for inclusion. The intervention will comprise six coaching sessions with the practice nurse in 9 months, seeking to increase PA in daily activities and using an activity tracker for goal setting and feedback. The Reach, Effectiveness, Adoption, Implementation and Maintenance framework will be used to evaluate implementation in terms of the health outcomes, extent of implementation and barriers and facilitators to implementation, using a mixed methods approach. Descriptive analyses and linear mixed model analyses will be performed on the quantitative data, while qualitative data from focus groups and interviews will be analysed by thematic analyses. ETHICS AND DISSEMINATION: The Medical Research Ethics Committee of the University Medical Centre Groningen, the Netherlands, concluded that this study was not subject to the Dutch Medical Research Involving Human Subjects Act (registration number: 201900586). The study results will be made available to patients and general practitioners via (inter)national publications and conferences, newsletters, public summaries and via (social) media.

Home-based Physical Activity to Alleviate Fatigue in Cancer Survivors: A Systematic Review and Meta-analysis.

PURPOSE: Physical activity (PA) affects fatigue and mental health in cancer survivors favorably, but participation in PA interventions tends to be low. More participants may be reached by home-based PA owing to greater accessibility and self-monitoring. This systematic review therefore evaluated the effects of home-based PA of low to moderate intensity on symptoms of fatigue, depression, and anxiety among cancer survivors. METHODS: PubMed, CINAHL, PsycINFO, and Web of Science were systematically searched for randomized controlled trials. We included investigations of home-based PA interventions in adults treated curatively for cancer and evaluating fatigue, depression, or anxiety as outcomes. We performed a random-effect meta-analysis for the effects of PA interventions on fatigue in the short and long terms. Subgroup analyses were performed for the frequency of counseling. Standardized mean differences (SMD) and 95% confidence intervals are reported. RESULTS: Eleven articles comprising 1066 participants were included: 77% had a history of breast cancer; 14%, ovarian cancer; 4%, colorectal cancer; 4%, prostate cancer; and 1%, "other" cancer (not specified). Concerning the outcomes, nine articles reported on fatigue and two reported on depression or anxiety. Meta-analyses showed a significant effect of home-based PA on fatigue immediately after the intervention (SMD = 0.22 [0.06-0.37]), at 3 months' follow-up (SMD = 0.27 [0.04-0.51]), and at 6-9 months' follow-up (SMD = 0.31 [0.08-0.55]). PA interventions that used frequent counseling were associated with larger improvements in fatigue than those using no or infrequent counseling. CONCLUSIONS: Home-based PA interventions can reduce fatigue among adult cancer survivors for up to 9 months, and frequent counseling may improve the benefits of these interventions.

A systematic review of the association between nursing staff and nursing-sensitive outcomes in long-term institutional care.

AIMS: To examine the association between type of nursing staff and nursing-sensitive outcomes in long-term institutional care. DESIGN: This systematic review included studies published in English, German, and Dutch between January 1997 and January 2020. DATA SOURCES: The databases Medline (PubMed), CINAHL, PsycINFO, Embase, and the Cochrane Library were searched. Original quantitative studies were included. REVIEW METHODS: The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were followed. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist was used to critically appraise the reporting of the studies. RESULTS: Fifteen articles were included. Of 33 quality of care outcomes, 21 were identified as nursing-sensitive outcomes of which 13 showed a significant association with nursing staff, specifically: Activities of daily living, aggressive behavior, bladder/bowel incontinence, contractures, expressive language skills, falls, infection (including vaccination), range of motion, pain, pressure ulcers, and weight loss. However, studies reported inconsistent results regarding the association among RNs, LPNs, CNAs, and HCAs and these nursing-sensitive outcomes, evidence shows that more RNs have a positive impact on nursing-sensitive outcomes. As to the evidence regarding the other type of nursing staff, especially HCA, findings regularly showed a negative association. CONCLUSION: Future research should be expanded with structure and process variables of which the mediating and moderating effect on nursing-sensitive outcomes is known. These may explain variances in quality of care and guide quality improvement initiatives. Researchers should consider fully applying Donabedian's structure-process-outcomes framework as it is a coherent entirety for quality assessment. IMPACT: This review provides an overview of quality of care outcomes that are responsive to nursing interventions in long-term institutional care. As the effects can be monitored and documented, quality assessment should focus on these nursing-sensitive outcomes. The inconclusive results make it difficult to provide recommendations on who should best perform which care.

The consistency between planned and actually given nursing care in long-terminstitutional care.

Continuous information exchange between healthcare professionals is facilitated by individualized care plans. Compliance with the planned care as documented in care plans is important to provide person-centered care which contributes to the continuity of care and quality of care outcomes. Using the Nursing Interventions Classification, this study examined the consistency between documented and actually provided interventions by type of nursing staff with 150 residents in long-term institutional care. The consistency was especially high for basic (93%) and complex (79%) physiological care. To a lesser extent for interventions in the behavioral domain (66%). Except for the safety domain, the probability that documented interventions were provided was high for all domains (≥ 91%, p > 0.05). NAs generally provided the interventions as documented. Findings suggest that HCAs worked beyond there scope of practice. The results may have implications for the deployment of nursing staff and are of importance to managers.

Accuracy of documentation in the nursing care plan in long-term institutional care.

Nursing staff working in long-term institutional care attend to residents with an increasing number of severe physical and cognitive limitations. To exchange information about the health status of these residents, accurate nursing documentation is important to ensure the safety of residents. This study examined the accuracy of nursing documentation in 197 care plans of five long-term institutional care facilities. Based on the phases of the nursing process, the D-Catch instrument measures the accuracy of the content and coherence of documentation. Inadequacies were especially found in the description of residents' care needs and stated nursing diagnoses as well as in progress and outcome reports. In somatic and psycho-geriatric units, higher accuracy scores were determined compared with residential care units. Investments in resources (e.g., time), reasoning skills of nursing staff, and implementation of professional standards in accordance with legal requirements may be needed to enhance the quality of nursing documentation.

Randomized Trial of a Lifestyle Program in Obese Infertile Women.

BACKGROUND: Small lifestyle-intervention studies suggest that modest weight loss increases the chance of conception and may improve perinatal outcomes, but large randomized, controlled trials are lacking. METHODS: We randomly assigned infertile women with a body-mass index (the weight in kilograms divided by the square of the height in meters) of 29 or higher to a 6-month lifestyle intervention preceding treatment for infertility or to prompt treatment for infertility. The primary outcome was the vaginal birth of a healthy singleton at term within 24 months after randomization. RESULTS: We assigned women who did not conceive naturally to one of two treatment strategies: 290 women were assigned to a 6-month lifestyle-intervention program preceding 18 months of infertility treatment (intervention group) and 287 were assigned to prompt infertility treatment for 24 months (control group). A total of 3 women withdrew consent, so 289 women in the intervention group and 285 women in the control group were included in the analysis. The discontinuation rate in the intervention group was 21.8%. In intention-to-treat analyses, the mean weight loss was 4.4 kg in the intervention group and 1.1 kg in the control group (P<0.001). The primary outcome occurred in 27.1% of the women in the intervention group and 35.2% of those in the control group (rate ratio in the intervention group, 0.77; 95% confidence interval, 0.60 to 0.99). CONCLUSIONS: In obese infertile women, a lifestyle intervention preceding infertility treatment, as compared with prompt infertility treatment, did not result in higher rates of a vaginal birth of a healthy singleton at term within 24 months after randomization.

Examining Time Use of Dutch Nursing Staff in Long-Term Institutional Care: A Time-Motion Study.

OBJECTIVES: Increasing residents' acuity levels and available resources in long-term institutional care requires insight into the care provided by nursing staff so as to guide task allocation and optimal use of resources, and enhance quality of care. The purpose of this study was to examine the relationship between time use and type of nursing staff, residents' acuity levels, and unit type by using a standardized nursing intervention classification. DESIGN: A multicenter cross-sectional observational study was performed using time-motion technique. SETTING: Five Dutch long-term institutional care facilities participated. In total, 4 residential care units, 3 somatic units, and 6 psycho-geriatric units were included. PARTICIPANTS: Data were collected from 136 nursing staff members: 19 registered nurses, 89 nursing assistants, 9 primary caregivers, and 19 health care assistants. MEASUREMENTS: A structured observation list was used based on the Nursing Interventions Classification (NIC). Residents' acuity levels, representing residents' needs, were based on the Dutch Care Severity Index. Medians and interquartile ranges were calculated for time spent on interventions per type of nursing staff and units. Linear mixed models were used to examine the relationship between time spent on nursing interventions and the type of nursing staff, residents' acuity levels, and unit type. RESULTS: Observations resulted in 52,628 registered minutes for 102 nursing interventions categorized into 6 NIC domains for 335 residents. Nursing staff spent the most time on direct care interventions, particularly in the domain of basic physiological care. Variances in time spent on interventions between types of nursing staff were minimal. Unit type was more significantly (P < .05) associated with time spent on interventions in domains than the type of nursing staff. Residents' acuity levels did not affect time spent by nursing staff (P > .05). CONCLUSION: The current study found limited evidence for task allocation between the types of nursing staff, which may suggest a blurring of role differentiation. Also, findings suggest that residents received similar care regardless of their needs, implying that care is predominantly task-oriented instead of person-centered. Managers may reconsider whether the needs of residents are adequately met by qualified nursing staff, considering the differences in education and taking into account increasing acuity levels of residents and available resources.

Effect of diagnosis with a chronic disease on physical activity behavior in middle-aged women.

OBJECTIVE: Although regular physical activity is an effective secondary prevention strategy for patients with a chronic disease, it is unclear whether patients change their daily physical activity after being diagnosed. Therefore, the aims of this study were to (1) describe changes in levels of physical activity in middle-aged women before and after diagnosis with a chronic disease (heart disease, diabetes, asthma, breast cancer, arthritis, depression); and to (2) examine whether diagnosis with a chronic disease affects levels of physical activity in these women. METHODS: Data from 5 surveys (1998-2010) of the Australian Longitudinal Study on Women's Health (ALSWH) were used. Participants (N=4840, born 1946-1951) completed surveys every three years, with questions about diseases and leisure time physical activity. The main outcome measure was physical activity, categorized as: nil/sedentary, low active, moderately active, highly active. RESULTS: At each survey approximately half the middle-aged women did not meet the recommended level of physical activity. Between consecutive surveys, 41%-46% of the women did not change, 24%-30% decreased, and 24%-31% increased their physical activity level. These proportions of change were similar directly after diagnosis with a chronic disease, and in the years before or after diagnosis. Generalized estimating equations showed that there was no statistically significant effect of diagnosis with a chronic disease on levels of physical activity in women. CONCLUSION: Despite the importance of physical activity for the management of chronic diseases, most women did not increase their physical activity after diagnosis. This illustrates a need for tailored interventions to enhance physical activity in newly diagnosed patients.

Changes in the endurance shuttle walk test in COPD patients with chronic respiratory failure after pulmonary rehabilitation: the minimal important difference obtained with anchor- and distribution-based method.

BACKGROUND: Although the endurance shuttle walk test (ESWT) has proven to be responsive to change in exercise capacity after pulmonary rehabilitation (PR) for COPD, the minimally important difference (MID) has not yet been established. We aimed to establish the MID of the ESWT in patients with severe COPD and chronic hypercapnic respiratory failure following PR. METHODS: Data were derived from a randomized controlled trial, investigating the value of noninvasive positive pressure ventilation added to PR. Fifty-five patients with stable COPD, GOLD stage IV, with chronic respiratory failure were included (mean (SD) FEV1 31.1 (12.0) % pred, age 62 (9) y). MID estimates of the ESWT in seconds, percentage and meters change were calculated with anchor based and distribution based methods. Six minute walking distance (6MWD), peak work rate on bicycle ergometry (Wpeak) and Chronic Respiratory Questionnaire (CRQ) were used as anchors and Cohen's effect size was used as distribution based method. RESULTS: The estimated MID of the ESWT with the different anchors ranged from 186-199 s, 76-82% and 154-164 m. Using the distribution based method the MID was 144 s, 61% and 137 m. CONCLUSIONS: Estimates of the MID for the ESWT after PR showed only small differences using different anchors in patients with COPD and chronic respiratory failure. Therefore we recommend using a range of 186-199 s, 76-82% or 154-164 m as MID of the ESWT in COPD patients with chronic respiratory failure. Further research in larger populations should elucidate whether this cut-off value is also valid in other COPD populations and with other interventions.

Selecting the increment size for a maximal incremental cycle test in patients with COPD.

Currently, to our knowledge, there are no chronic obstructive pulmonary disease (COPD)-specific formulas to predict the maximum workload of an incremental cycle ergometer test. The aim of the study was to investigate different prediction models including COPD-specific variables of maximum workload in 113 mild to very severe COPD patients. This study shows that simple measures like forced expiratory volume in 1 s, chair-stand test and modified Medical Research Council dyspnoea score may improve the accuracy of the predicted maximum workload in COPD patients.

Short- and long-term effects of a physical activity counselling programme in COPD: a randomized controlled trial.

BACKGROUND: We were interested in the effects of a physical activity (PA) counselling programme in three groups of COPD patients from general practice (primary care), outpatient clinic (secondary care) and pulmonary rehabilitation (PR). METHODS: In this randomized controlled trial 155 COPD patients, 102 males, median (IQR) age 62 (54-69) y, FEV1predicted 60 (40-75) % were assigned to a 12-weeks' physical activity counselling programme or usual care. Physical activity (pedometer (Yamax SW200) and metabolic equivalents), exercise capacity (6-min walking distance) and quality of life (Chronic Respiratory Questionnaire and Clinical COPD Questionnaire) were assessed at baseline, after three and 15 months. RESULTS: A significant difference between the counselling and usual care group in daily steps (803 steps, p = 0.001) and daily physical activity (2214 steps + equivalents, p = 0.001)) from 0 to 3 months was found in the total group, as well as in the outpatient (1816 steps, 2616 steps + equivalents, both p = 0.007) and PR (758 steps, 2151 steps + equivalents, both p = 0.03) subgroups. From 0 to 15 months no differences were found in physical activity. However, when patients with baseline physical activity>10,000 steps per day (n = 8), who are already sufficiently active, were excluded, a significant long-term effect of the counselling programme on daily physical activity existed in the total group (p = 0.02). Differences in exercise capacity and quality of life were found only from 0 to 3 months, in the outpatient subgroup. CONCLUSION: Our PA counselling programme effectively enhances PA level in COPD patients after three months. Sedentary patients at baseline still benefit after 15 months.

Physical activity recommendations in patients with chronic obstructive pulmonary disease.

BACKGROUND: Physical activity recommendations are hardly studied in patients with chronic obstructive pulmonary disease (COPD), and specifically recommendations that are individualized to a patient's aerobic fitness level are not studied. OBJECTIVES: To compare individualized (relative) and nonindividualized (absolute) physical activity recommendations in patients with COPD and to assess whether there are differences between patients with mild to moderate and (very) severe COPD. METHODS: We compared 7 different physical activity recommendations that were described in the literature. Four recommendations were individualized based on the patient's aerobic fitness level measured by a maximal cycle ergometer test. Three recommendations were nonindividualized. The recommendations were measured with an accelerometer, pedometer or questionnaire in 115 patients with mild to very severe COPD (68% male, mean age 65 years, mean FEV1 58% predicted). RESULTS: The percentage of patients that met the different recommendations ranged from 22 to 86% and only 8 patients met all 7 recommendations. The agreement between the different recommendations was poor (intraclass correlation coefficient, 0.28). Individualizing the recommendations resulted in a higher number of patients with severe or very severe COPD meeting the individualized recommendations compared to the nonindividualized recommendations. In contrast, patients with mild to moderate COPD less frequently met the individualized recommendations. CONCLUSIONS: Our study showed that applying various physical activity recommendations with small differences in frequency, intensity or time led to large differences in the classification of patients with COPD into being sufficiently physically active or not. Consequently, the used recommendation will highly affect the proposed physical activity advice to the patient.

Daily physical activity in stable heart failure patients.

BACKGROUND: Physical activity is the only nonpharmacological therapy that is proven to be effective in heart failure (HF) patients in reducing morbidity. To date, little is known about the levels of daily physical activity in HF patients and about related factors. OBJECTIVE: The objectives of this study were to (a) describe performance-based daily physical activity in HF patients, (b) compare it with physical activity guidelines, and (c) identify related factors of daily physical activity. METHODS: The daily physical activity of 68 HF patients was measured using an accelerometer (SenseWear) for 48 hours. Psychological characteristics (self-efficacy, motivation, and depression) were measured using questionnaires. To have an indication how to interpret daily physical activity levels of the study sample, time spent on moderate- to vigorous-intensity physical activities was compared with the 30-minute activity guideline. Steps per day was compared with the criteria for healthy adults, in the absence of HF-specific criteria. Linear regression analyses were used to identify related factors of daily physical activity. RESULTS: Forty-four percent were active for less than 30 min/d, whereas 56% were active for more than 30 min/d. Fifty percent took fewer than 5000 steps per day, 35% took 5000 to 10 000 steps per day, and 15% took more than 10 000 steps per day. Linear regression models showed that New York Heart Association classification and self-efficacy were the most important factors explaining variance in daily physical activity. CONCLUSIONS: The variance in daily physical activity in HF patients is considerable. Approximately half of the patients had a sedentary lifestyle. Higher New York Heart Association classification and lower self-efficacy are associated with less daily physical activity. These findings contribute to the understanding of daily physical activity behavior of HF patients and can help healthcare providers to promote daily physical activity in sedentary HF patients.

Are grown-ups with congenital heart disease willing to participate in an exercise program?

OBJECTIVE: To examine the willingness of grown-ups with congenital heart disease (GUCH) to participate in the GUCH Training Program-Individualised (GTI), an exercise program specifically designed for GUCH, and to identify factors affecting their willingness to participate. DESIGN AND SETTING: In this cross-sectional study, all outpatient GUCH of the University Medical Center Groningen in The Netherlands, living within a 30-km radius of Groningen (n = 311), were asked to participate. PATIENTS: In total, 116 (37%) of the 311 GUCH who are invited to participate in our study returned completed questionnaires. The median age of the respondents was 40 (interquartile range 31-50) years and 55% were women. OUTCOME MEASURES: Respondents (n = 116) completed a questionnaire that queried physical activity, perceived physical fitness, psychosocial determinants (motivation, self-efficacy, and social support) related to physical activity, and willingness to participate in GTI. RESULTS: Of the 116 respondents, 68 (59%) were willing to participate in GTI. They were less physically active, had worse perceived physical fitness, were less satisfied with their fitness, were generally more motivated to engage in physical activity, and had more social support than patients unwilling to participate. The best logistic regression model predicting willingness to participate in GTI included the variables perceived physical fitness and motivation for physical activity in general. CONCLUSIONS: Asking GUCH to participate in an exercise program supervised by physical therapists is a good strategy. Taken into account nonresponse, a participation rate in the exercise program of over 20% is to be expected. Perceived physical fitness and motivation for physical activity in general are important predictors of patients' willingness to participate.

Functional and psychological variables both affect daily physical activity in COPD: a structural equations model.

BACKGROUND: Daily physical activity (DPA) level is reduced in patients with COPD. The aim of this study was to investigate the association of DPA with functional and psychological variables in these patients. METHODS: 155 COPD patients (102 males, median (IQR) age 62 years (54-69 years), predicted FEV1 60% (40-75%) were included. We assessed DPA (DigiWalker SW-200), functional capacity and psychological factors. RESULTS: DPA level was significantly associated with all functional capacity variables and two psychological variables (Perceived Physical Ability Subscale, depression subscale of the Hospital Anxiety and Depression Scale). The six-minute walking distance and St. George Respiratory Questionnaire activity score explained 37% of the variance of DPA in a regression analysis. A structural equations model revealed that psychological variables indirectly explained DPA through functional capacity variables. DPA was stronger associated with functional capacity variables and weaker with psychological variables in patients with lower functional status than in patients with higher functional status. CONCLUSIONS: Higher levels of DPA are associated with better functional capacity, but interestingly, DPA is also affected by psychological factors, though only indirectly, via functional capacity. The effect of specific treatment addressing psychological factors on DPA level and exercise tolerance needs further investigation. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT00614796.

Self-efficacy for physical activity and insight into its benefits are modifiable factors associated with physical activity in people with COPD: a mixed-methods study.

QUESTIONS: What are the perceived reasons for people with chronic obstructive pulmonary disease (COPD) to be physically active or sedentary? Are those reasons related to the actual measured level of physical activity? DESIGN: A mixed-methods study combining qualitative and quantitative approaches. PARTICIPANTS: People with mild to very severe COPD. OUTCOME MEASURES: Participants underwent a semi-structured interview and physical activity was measured by a triaxial accelerometer worn for one week. RESULTS: Of 118 enrolled, 115 participants (68% male, mean age 65 years, mean FEV1 57% predicted, mean modified Medical Research Council dyspnoea score 1.4) completed the study. The most frequently reported reason to be physically active was health benefits, followed by enjoyment, continuation of an active lifestyle from the past, and functional reasons. The most frequently reported reason to be sedentary was the weather, followed by health problems, and lack of intrinsic motivation. Mean steps per day ranged between 236 and 18 433 steps. A high physical activity level was related to enjoyment and self-efficacy for physical activity. A low physical activity level was related to the weather influencing health, financial constraints, health and shame. CONCLUSION: We identified important facilitators to being physically active and barriers that could be amenable to change. Furthermore, we distinguished three important potential strategies for increasing physical activity in sedentary people with COPD, namely reducing barriers and increasing insight into health benefits, tailoring type of activity, and improvement of self-efficacy.

Measurement of acute nonspecific low back pain perception in primary care physical therapy: reliability and validity of the brief illness perception questionnaire.

BACKGROUND: The eight-item Brief Illness Perception Questionnaire is used as a screening instrument in physical therapy to assess mental defeat in patients with acute low back pain, besides patient perception might determine the course and risk for chronic low back pain. However, the psychometric properties of the Brief Illness Perception Questionnaire in common musculoskeletal disorders like acute low back pain have not been adequately studied. Patients' perceptions vary across different populations and affect coping styles. Thus, our aim was to determine the internal consistency, test-retest reliability and validity of the Dutch language version of the Brief Illness Perception Questionnaire in acute non-specific low back pain patients in primary care physical therapy. METHODS: A non-experimental cross-sectional study with two measurements was performed. Eighty-four acute low back pain patients, in multidisciplinary health care center in Dutch primary care with a sample mean (SD) age of 42 (12) years, participated in the study. Internal consistency (Cronbach's α) and test-retest procedures (Intraclass Correlation Coefficients and limits of agreement) were evaluated at a one-week interval. The concurrent validity of the Brief Illness Perception Questionnaire was examined by using the Mental Health Component of the Short Form 36 Health Survey. RESULTS: The Cronbach's α for internal consistency was 0.73 (95% CI, 0.67 - 0.83); and the Intraclass Correlation Coefficient test-retest reliability was acceptable: 0.72 (95% CI, 0.53 - 0.82), however, the limits of agreement were large. The Intraclass Correlation Coefficient measuring concurrent validity 0.65 (95% CI, 0.46 - 0.80). CONCLUSION: The Dutch version of the Brief Illness Perception Questionnaire is an appropriate instrument for measuring patients' perceptions in acute low back pain patients, showing acceptable internal consistency and reliability. Concurrent validity is adequate, however, the instrument may be unsuitable for detecting changes in low back pain perception over time.
