Development and psychometric evaluation of the Thai Human Papillomavirus Beliefs Scale

In this study, we developed and evaluated the psychometric properties of the Thai Human Papillomavirus Beliefs Scale. The Scale was tested on 386 young women aged 18-24 years in Chiang Mai, Thailand. Content validity of the Scale was evaluated by a panel of experts, construct validity was determined using exploratory factor analysis, and reliability was assessed for stability and internal consistency. Factor analysis provided empirical support for the existence of four factors, which accounted for 67.7% of the total variance: perceived susceptibility, perceived seriousness, perceived benefits, and perceived barriers. Cronbach's α reliability coefficients for the four subscales ranged from 0.59 to 0.86. Factors predicting intention to receive the papillomavirus vaccine were perceived susceptibility, perceived benefits, and perceived barriers. The Thai Human Papillomavirus Beliefs Scale demonstrated promising psychometric properties, indicating that it might be a useful instrument for assessing young women's human papillomavirus and cervical cancer-associated beliefs, and for predicting human papillomavirus vaccination intention.     

Motivators and barriers of a Healthy Lifestyle Scale: development and psychometric characteristics

Black individuals suffer disproportionately from diseases that are preventable by lifestyle choices. The purpose of this study was to test the internal consistency and construct validity of the newly devised instrument, Motivators and Barriers of a Healthy Lifestyle Scale (MABS). The MABS was administered to 109 community-dwelling, adult Blacks. Content validity was supported through review of the literature and the judgment of three content experts. Exploratory factor analysis supported the two dimensions, that is, motivators and barriers. The Cronbach's alphas for the motivators and barriers dimensions were .88 and .90, respectively. Results provide initial evidence that the MABS is a valid, internally consistent measure of factors that motivate or inhibit healthy lifestyle behaviors. Screening with the MABS could encourage more focused health promotion discussions between patients and practitioners.     

Validation evidence for Turkish adaptation of Champion's Health Belief Model Scales

Instruments using Health Belief Model constructs in breast cancer screening in previous studies were developed and tested by Champion for American women, and since then, these have been revised twice. Champion's Health Belief Model Scale (CHBMS) has been translated and tested in various studies in other countries and cultures. Also, the current study examined the validity and reliability of the Turkish adaptation of the CHBMS among Turkish women. The instrument was translated using a back-translation technique, which includes the use of a panel of experts and interpreters to translate the items from the source language to the target language and then back-translate them to the source language. The study was conducted in Ordu, a city in north Turkey. A total of 266 Turkish women aged 20 and older working as primary schoolteachers were included in the sample. Analyses included internal consistency, reliability, factor analysis, and known group techniques. After the analysis, 3 items from the Barriers domain, 1 from the Seriousness domain, and 2 from the Motivation domain were deleted from the original scale. So, the final Turkish version of the CHBMS (CHBMS-T) consisted of 36 items that were clustered into 6 subscales: susceptibility (3 items), seriousness (6 items), motivation (5 items), benefits of breast self-examination (BSE) (4 items), barriers to BSE (8 items), and confidence/self-efficacy of BSE (10 items). Internal consistency ranged from 0.69 to 0.83. Construct validity was supported by exploring the factor structure of the instrument using factor analysis and testing known-group techniques. Psychometric testing demonstrated satisfactory internal consistency and validity of the instrument for this group of women. It can be used in planning and testing interventions to improve BSE beliefs and practice.     

Development and psychometric testing of the rural pregnancy experience scale (RPES)

Rural pregnant woman who lack local access to maternity care due to their remote living circumstances may experience stress and anxiety related to pregnancy and parturition. The Rural Pregnancy Experience Scale (RPES) was designed to assess the unique worry and concerns reflective of the stress and anxiety of rural pregnant women related to pregnancy and parturition. The items of the scale were designed based on the results of a qualitative study of the experiences of pregnant rural women, thereby building a priori content validity into the measure. The relevancy content validity index (CVI) for this instrument was 1.0 and the clarity CVI was .91, as rated by maternity care specialists. A field test of the RPES with 187 pregnant rural women from British Columbia indicated that it had two factors: financial worries and worries/concerns about maternity care services, which were consistent with the conceptual base of the tool. Cronbach's alpha for the total RPES was .91; for the financial worries subscale and the worries/concerns about maternity care services subscale, alpha were .89 and .88, respectively. Construct validity was supported by significant correlations between the total scores of the RPES and the Depression Anxiety Stress Scales (DASS [r =.39, p < .01]), and subscale scores on the RPES were significantly correlated and converged with the depression, anxiety, and stress subscales of the DASS supporting convergent validity (correlations ranged between .20; p < .05 and .43; p < .01). Construct validity was also supported by findings that the level of access and availability of maternity care services were significantly associated with RPES scores. It was concluded that the RPES is a reliable and valid measure of worries and concerns reflective of rural pregnant women's stress and anxiety related to pregnancy and parturition.     

Benefits of and barriers to dietary sodium adherence

Failure to limit dietary sodium leads to thirst, large fluid weight gain, and poor outcomes in patients receiving hemodialysis. Perceived benefits and barriers may influence adherence; however, tools measuring these relationships are not available. This study's purpose, based on the health belief model, was to evaluate the reliability and validity of the Beliefs about Dietary Compliance Scale (BDCS), describe perceived benefits and barriers over time, and identify individual benefits and barriers that may be amenable to tailored interventions. A convenience sample of 229 completed the BDCS at baseline. One week after baseline, 52 participants completed the BDCS to assess test-retest reliability. Four months after baseline, 187 participants (81%) remained. Cronbach's alphas for the scale ranged from .66 to .81. One-week test-retest reliabilities ranged from .68 to .86. Factor structure was supported by factor analysis. Scores remained stable over time. Barriers to dietary sodium limitations were common and more in need of intervention.     

Psychometric assessment of the Adolescent Physical Activity Perceived Benefits and Barriers Scales

The purpose of this study was to psychometrically test the Adolescent Physical Activity Perceived Benefits and Barriers Scales developed for middle-school-age youth. A total of 206 racially diverse 6th, 7th, and 8th graders completed questionnaires at two time points (2 weeks apart). For the 10-item Perceived Benefits Scale and the 9-item Perceived Barriers Scale, test-retest reliability (r = .70; r = .71, respectively) and internal consistency (Cronbach's alpha was .80 and .79, respectively, at time 1) were supported. Principal components analysis with Varimax rotation was employed to assess construct validity. A 2-factor solution emerged for each scale as predicted. The relationship between both scale scores and self-reported physical activity provided additional evidence of validity. Both instruments were found to be reliable and valid for measuring the perceived benefits of and barriers to physical activity in middle school youth.     

Development and psychometric evaluation of the Dialysis patient-perceived Exercise Benefits and Barriers Scale

Background

Perceptions of exercise benefits and barriers affect exercise behavior. Because of the clinical course and treatment, dialysis patients differ from the general population in their perceptions of exercise benefits and barriers, especially the latter. At present, no valid instruments for assessing perceived exercise benefits and barriers in dialysis patients are available.

Objectives

Our goal was to develop and test the psychometric properties of the Dialysis patient-perceived Exercise Benefits and Barriers Scale (DPEBBS).

Methods

A literature review and two focus groups were conducted to generate the initial item pool. An expert panel examined the content validity. Then, 269 Chinese hemodialysis patients were recruited by convenience sampling. Exploratory and confirmatory factor analyses were used to test construct validity. Finally, internal consistency and test-retest reliability were assessed.

Results

The expert panel determined that the content validity index was satisfactory. The final 24-item scale consisted of six factors explaining 57% of the total variance in the data. Confirmative factor analysis supported the six-factor structure and a higher-order model. Cronbach's alpha was 0.87 for the total scale, and 0.84 for test-retest reliability.

Conclusion

The DPEBBS was a valid and reliable instrument for evaluating dialysis patients’ perceived benefits and barriers to exercise. The application value of this scale remains to be investigated by increasing the sample size and evaluating patients undergoing different dialysis modalities and coming from different regions and cultural backgrounds.     

Barriers to Pain Management among Adolescents with Cancer

Patient-related barriers to reporting pain and using analgesics (e.g., fear of addiction) can detrimentally affect pain management for adolescents with cancer. However, adolescent barriers have not been systematically investigated; furthermore, no instrument exists to measure these barriers. The purposes of this study were to examine the psychometric properties of the newly developed Adolescent Barriers Questionnaire (ABQ) and to describe adolescent barriers to pain management. The study was guided by a barriers model which suggests that barriers (beliefs) influence coping (hesitation to report pain, use of analgesics, and adequacy of analgesics), which in turn affects outcomes (pain severity and quality of life). Sixty adolescent patients with cancer aged 12-17 years completed the ABQ; 22 of which reported pain and also completed measures of hesitation, analgesic use, pain severity, and physical and psychosocial function. Initial testing provided evidence that the ABQ is reliable and valid. Internal consistency estimates for the total scale ranged from 0.91 to 0.94 and for the subscales ranged from 0.54 to 0.96. Test-retest reliability over a 2-week period was r = 0.82. Construct validity was supported by a significant positive relationship between barriers scores and coping (hesitation to report pain and to use analgesics). However, coping did not mediate the relationship between barriers and outcomes. All of the adolescents reported some barriers. Barriers scores did not vary by age or gender. The leading barrier was concern that social activities would be restricted if pain was reported. Clearly, adolescents have barriers that can interfere with pain management. Interventions are needed to identify and help adolescents overcome these barriers.     

Adaptation and psychometric evaluation of the Swedish version of the Good Nursing Care Scale for Patients

The aim of this study was to adapt the instrument 'Good Nursing Care Scale for Patients' to Swedish conditions as a measure of patients' satisfaction, as well as estimating its reliability and validity. Following a pilot test, discussions in the author group, testing for readability among patients and judgement of content validity by a panel of experts, the final version was reduced to 72 items focusing on good caring. The refined instrument was assessed for internal consistency in 447 surgical in-patients, for 2 week test-retest reliability in 100 patients and subjected to orthogonal principal components factor analysis with varimax rotation, followed by second-order factor analysis. The internal consistency item-item correlation coefficient ranged from 0.15 to 0.91, correlation between each item and the total scale was >or=0.30 for 70 items, Cronbach's alpha coefficient for the final scale was 0.79 and test-retest reliability was 0.75. An orthogonal principal components factor analysis with varimax rotation was conducted on the final 71 items and the 15 first-order factors with eigenvalues >or=1 explained 66% of the total variance. A second-order factor analysis of these 15 factors as items resulted in a seven-factor solution. The total variance explained by the seven factors was 79%. Cronbach's alpha coefficient for the seven factors ranged between 0.32 and 0.95. The instrument seems reliable and valid to assess the patients' satisfaction with what happened during their hospital stay. To confirm the factor structure and improve factor consistency additional development and testing is suggested.     

Psychometric assessment of the Postpartum Depression Predictors Inventory-Revised

Identification of women at risk for postpartum depression requires reliable and valid assessment indices. The purpose of this article is to describe the psychometric properties of the Postpartum Depression Predictors Inventory-Revised (PDPI-R). Psychometric assessment of the PDPI-R was conducted in conjunction with the Centers for Epidemiologic Studies Depressed Mood Scale, and the Edinburgh Postnatal Depression Scale, using data from 139 pregnant women who were followed for 8 months after birth. The prenatal PDPI-R demonstrated concept, concurrent, and predictive validity. The postpartum PDPI-R demonstrated concurrent validity. Factor analysis revealed four underlying factors that did not match the original conceptualization of the instrument. Reliability of the total score resulting from the factor analysis was .83. Initial support for the reliability and validity of the PDPI-R was indicated.     

Development and Validation of a Questionnaire to Assess Barriers to Physical Activity After Stroke: The Barriers to Physical Activity After Stroke Scale

ObjectiveTo develop and validate a self-reported questionnaire assessing the barriers to physical activity (PA) among stroke survivors.DesignPsychometric study.SettingAmbulatory stroke care.ParticipantsA total of one hundred and forty-six (N=146) individuals were included in this study. In stage 1, community-living stroke survivors (n=37; 13 women) with low-moderate disability (modified Rankin Score 0-3, stroke >3mo) were included. In stage 2, participants (n=109; 40 women) with same characteristics were included. Nine professionals experienced in PA for poststroke patients formed an expert panel.InterventionsIn stage 1, semistructured interviews identified perceived barriers to PA, which were then selected by the expert panel and grouped on a Barriers to Physical Activity After Stroke (BAPAS) scale. In stage 2, stroke participants completed a personal information questionnaire and the BAPAS scale.Main Outcome MeasuresAn item selection process with factor analysis was carried out. The suitability of the data set was analyzed using the Kaiser-Meyer-Olkin coefficient, internal consistency was evaluated by Cronbach α, and concurrent validity was assessed with Spearman correlation coefficients between the BAPAS scale and the modified Rankin Scale. Test-retest repeatability was estimated using 2-way random effects intraclass correlation coefficient model 2,1 at 4-6 day follow-up (n=21).ResultsFactor analysis supported a 14-item BAPAS that explained 62% of total variance (Kaiser-Meyer-Olkin=0.82) and total score calculated higher than 70 (higher scores for higher barriers). Cronbach α was 0.86, Spearman correlation with the modified Rankin Scale was r=0.65 (P<.001), and test-retest intraclass correlation coefficient was 0.91 (95% CI, 0.79-0.97). The BAPAS scores were higher in patients with greater disabilities and in those with a longer time since the stroke event (P<.01).ConclusionWe developed and validated the BAPAS scale to assess barriers to PA in stroke survivors with low-moderate disability with promising psychometric properties.

Cross-Cultural Adaptation and Validation of the Nepali Version of the Pelvic Girdle Questionnaire

ObjectiveThe purpose of this study was to translate, cross-culturally adapt, and assess the reliability and validity of the Pelvic Girdle Questionnaire (PGQ) in pregnant Nepalese women.MethodsThe cross-cultural adaptation process was conducted according to the Guillemin guidelines. Reliability and validity were assessed using cross-sectional design. The participants responded to questionnaires of sociodemographics, the Nepali version of the PGQ, the Oswestry Disability Index, the Patient-Specific Functional Scale, the 5-item version of the Edinburgh Depression Scale, and the Numerical Pain Rating Scale. The internal consistency was assessed with Cronbach's alpha. The test–retest reliability was calculated using the intraclass correlation coefficient and smallest detectable change. Construct validity was assessed by testing 9 a priori hypotheses that examine correlations between the PGQ activity and symptom subscales, and also among the PGQ subscales and Oswestry Disability Index, Numerical Pain Rating Scale, Patient-Specific Functional Scale, and 5-item version of the Edinburgh Depression Scale. Spearman and Pearson's correlation were used to assess the correlations.ResultsA sample of 111 pregnant women were included in the study. The Cronbach's alpha for the Nepali version of the total PGQ was good (α = 0.83), and the test–retest reliability was acceptable (ICC_2.1, 0.72) with a measurement error of SDC_95% 18.6 points. Seven of the 9 hypotheses found support, which confirms acceptable construct validity of the Nepali PGQ.ConclusionThe Nepali version of the PGQ is a reliable and valid tool for assessing pelvic girdle pain in pregnant Nepalese women.     

Primary emotions in patients after myocardial infarction

AIMS: This paper reports a study testing the reliability and validity of the Emotion and Health Scale and to check convergent and discriminant validity against the Hospital Anxiety and Depression Scale. BACKGROUND: Reactions to illness are often measured in the narrow terms of anxiety and depression. Primary emotions are claimed by the functionalist school of psychology to be adaptive and to produce specific behaviours for survival. The functionalist theory requires testing in the context of health threat and adaptation. This paper is concerned with the development of a 24-item self-assessment scale of eight primary emotions. METHODS: A healthy cohort of 150 university students was enrolled to complete the Health and Emotion Scale. A cohort of 80 first-time myocardial infarction patients was enrolled to complete the Emotion and Health Scale and the Hospital Anxiety and Depression Scale four days after the onset of myocardial infarction or when symptoms were controlled. The data were collected in 2002. RESULTS: The Emotion and Health Scale was shown to have acceptable internal consistency. Significant differences were observed between the healthy and myocardial infarction cohorts in illness attributed sadness, anger, disgust and surprise. Healthy men had significantly more health fear than women. CONCLUSIONS: The Emotion and Health Scale is a valid and reliable instrument that could be used to study emotion and illness. This line of enquiry may improve understanding of illness reactions and the role primary emotions exert on adaptation to health change.

Psychometric properties of a Symptom Management Self-Efficacy Scale for women living with HIV/AIDS

ContextMany people with HIV/AIDS find it difficult to manage the symptoms of the disease, but by adopting effective symptom management behavior, they increase the potential of alleviating the burden of those symptoms. Self-efficacy is a recognized mediator of successful behavior change and is used by many researchers and clinicians when developing symptom management interventions. Despite this, an instrument measuring the self-efficacy of symptom management behavior specifically for people living with HIV/AIDS has not yet been made available.ObjectivesTo introduce and test the psychometric properties of the HIV Symptom Management Self-Efficacy for Women Scale (HSM-SEWS) for women with HIV/AIDS. This scale, a new nine-item measurement instrument, was modified from the Chronic Disease Self-Efficacy Scale.MethodsIn this study, psychometric testing focused on the reliability and validity of the HSM-SEWS instrument. Reliability was assessed using Cronbach’s alpha. Exploratory factor analysis with oblique promax rotation was used to examine validity and test hypothetical associations.ResultsEighty-nine HIV-positive women were recruited and asked to complete the scale every four weeks for a total of 16 weeks. Factor analysis supported a one-factor solution explaining 93% of the variance among items. Internal consistency of the nine items was found to range from 0.83 to 0.93, with an overall Cronbach’s alpha of 0.92.ConclusionPsychometric analyses suggest that the HSM-SEWS is a reliable and valid instrument that measures the self-efficacy of symptom management behavior in women with HIV/AIDS and can be used during interventions and in studies targeting this area of health care research.     

Translation and validation of champion's health belief model scale with Korean women

The Champion's Health Belief Model Scale (CHBMS) is a reliable and valid instrument developed for American women to measure beliefs about breast cancer and breast self-examination. The purpose of this study is to translate the CHBMS into Korean and to validate the scale among Korean women. The CHBMS was translated using a back-translation technique. A convenience sample of 264 women was recruited from a continuing education center, a community health center, and a university in 3 South Korean cities. The participants were asked to complete the translated Korean version of the CHBMS questionnaire. The data obtained were analyzed using a principal component analysis with varimax rotation for construct validity. Loading criterion was set at.45. Cronbach's alpha was computed for the reliability of the scale. From the analysis, two items from the Benefits domain and four items from the Motivation domain were deleted from the original scale. Thus, the final Korean version of the CHBMS (CHBMS-K) consisted of 36 items that were clustered to 6 subscales: susceptibility (5 items), seriousness (7 items), benefits (4 items), barriers (6 items), confidence (11 items), and motivation (3 items). Cronbach's alpha reliability coefficients for the 6 subscales ranged from.92 to.72. The CHBMS-K was found to be reliable and valid in scale for use with Korean women. It can be used in planning and testing interventions to improve breast self-examination beliefs and practice.     

A validity and reliability study investigating the Turkish version of the Infant Colic Scale.

The Infant Colic Scale is used to diagnose colic and to determine factors that cause colic. This study aimed to establish the validity and reliability of the Infant Colic Scale for the Turkish population. The research sample included mothers (N = 110) of 132 infants with colic registered at three public health clinics in the Denizli province. Language validity, content validity, and construct validity were examined. On the basis of the Infant Colic Scale's internal consistency reliability analysis, three items were removed. Factor analysis resulted in five subscales. The Cronbach's alpha coefficients were .55 to .89 for the subscales, and .73 for the total scale. The scale's test-retest reliability was .65. The Infant Colic Scale was found to be a valid and reliable measurement tool for the Turkish population.
