Adolescent health promotion scale: development and psychometric testing

The purpose of this study was to assess the psychometric properties of a newly devised instrument, the Adolescent Health Promotion scale (AHP), a 40-item Likert-type self-report instrument used to detect unhealthy lifestyles in adolescents. Content validity was considered to be supported based on the findings of previous studies and the observations of a panel of 14 content experts. This study examined the construct validity and reliability of the instrument. The psychometric properties of the AHP, including item analysis, factor analysis, and reliability measures, were assessed based on the responses of 1,128 Taiwanese adolescents. Kaiser-Meyer-Olkin (KMO) measures and Bartlett's sphericity test showed that the samples met the criteria for factor analysis. Factor analysis yielded a six-factor instrument that explained 51.14% of the variance in the 40 items. The six factors were social support, life appreciation, health responsibility, nutritional behaviors, exercise behaviors, and stress management. The Cronbach alpha reliability coefficient for the total scale was 0.932, and alpha coefficients for the subscales ranged from 0.75 to 0.88. The results of this study indicate that the AHP has good construct validity and reliability in Taiwanese and that its use by school health nurses to assess adolescent health promotion programs is warranted.     

Development and testing of a patient‐centred care competency scale for hospital nurses

This study aimed to develop and test the psychometric soundness of a patient‐centred care competency (PCC) scale for hospital nurses. A cross‐sectional questionnaire survey was conducted among 594 nurses in two teaching hospitals (response rate 99.5%). Reliability and validity analyses were performed. The PCC scale consisted of 17 items divided into four subscales: respecting patients' perspectives (6 items), promoting patient involvement in care processes (5 items), providing for patient comfort (3 items) and advocating for patients (3 items). The Cronbach's alpha coefficient of the entire scale was 0.92, and those for the subscales were 0.85, 0.81, 0.84 and 0.80, respectively. Multitrait scaling analysis indicated that the four subscales had satisfactory convergent and discriminant validity. Significant correlations were found between total PCC scores and overall self‐ratings of patient‐centred care performance (r = 0.60, P < 0.001). The PCC scale was therefore determined to be a highly valid and reliable tool.

Quality of life in Polish respondents: psychometric properties of the Polish WHOQOL-Bref

The aim of this study was to examine the validity and reliability of the Polish WHOQOL - Bref in a sample of 908 respondents. The Bref is a generic quality of life (QoL) instrument designed for cross - cultural use. Correlational and multivariate analyses confirmed the relevancy of individual items and domains supporting the construct validity of the scale. Multiple regression analyses of the domain scores with two overall questions (dependent variable) showed that all four domains made a significant contribution in explaining the variance in overall QoL. The psychological domain made the strongest contribution (unstandardized B coefficient = 0.10, r2 = 0.41), followed by the social, environmental and physical domains. When overall health satisfaction was considered as the dependent variable, the physical domain contributed most strongly (unstandardized B coefficient = 0.21, r2= 0.43) followed by the psychological and environmental domains. Exploratory factor analyses resulted in a four factors solution with 24 items explaining 49.6% of the cumulative variance. Confirmatory factor analyses lended marginal support for the goodness of fit of the four-domain model. The physical domain was found to be strongest in differentiating between unhealthy and healthy subjects, followed by psychological and social domains. Acceptable internal consistency was shown with Cronbach's alpha coefficients being greater than 0.70 for all domains with the exception of the social domain. Further exploration of the scales validity and conceptual clarity need further testing in Polish and international samples.     

Preliminary Validation of Subjective Anchor Scales for Worry and Rumination

This research is a preliminary validation of two single-item visual analogue scales. The worry visual analogue scale (WVAS) and the rumination visual analogue scale (RVAS) are self-report measures developed to track state changes in worry and rumination. Each of these scales uses an idiographic anchor sheet, enabling each participant to quantify their personal scale of worry or rumination. We compared ratings on the WVAS and RVAS with self-report measures of trait worry and rumination as well as other constructs administered concurrently in two separate studies. In study 1 we compared results within an unselected undergraduate sample. In study 2 we compared results within a community-based sample of individuals with generalized anxiety disorder (GAD), individuals with GAD comorbid with unipolar depressive disorders, and healthy controls. Results from both studies indicate the WVAS is a reliable state-level measure of worry with acceptable discriminant and convergent validity. Results for the RVAS showed similar reliability and convergent validity but lacked as much discriminant validity. This difference is possibly due to all experimental groups having comorbid anxiety, which is associated more with worry than rumination. Regression analyses indicate the WVAS predicts trait-level anxiety measures more strongly than measures of depression and beyond the predictive ability of the RVAS. The RVAS predicts measures of depression more strongly than it does measures of anxiety but is not consistently a stronger predictor of depression than the WVAS. These findings suggest worry and rumination are distinct regulatory constructs. In study 2, participants with GAD, and GAD comorbid with unipolar depressive disorders, scored significantly higher than healthy controls in worry and rumination. The internal reliability of the measures is reported.     

The relationship between TV/computer time and adolescents' health-promoting behavior: a secondary data analysis

Television and computers provide significant benefits for learning about the world. Some studies have linked excessive television (TV) watching or computer game playing to disadvantage of health status or some unhealthy behavior among adolescents. However, the relationships between watching TV/playing computer games and adolescents adopting health promoting behavior were limited. This study aimed to discover the relationship between time spent on watching TV and on leisure use of computers and adolescents' health promoting behavior, and associated factors. This paper used secondary data analysis from part of a health promotion project in Taoyuan County, Taiwan. A cross-sectional design was used and purposive sampling was conducted among adolescents in the original project. A total of 660 participants answered the questions appropriately for this work between January and June 2004. Findings showed the mean age of the respondents was 15.0 +/- 1.7 years. The mean numbers of TV watching hours were 2.28 and 4.07 on weekdays and weekends respectively. The mean hours of leisure (non-academic) computer use were 1.64 and 3.38 on weekdays and weekends respectively. Results indicated that adolescents spent significant time watching TV and using the computer, which was negatively associated with adopting health-promoting behaviors such as life appreciation, health responsibility, social support and exercise behavior. Moreover, being boys, being overweight, living in a rural area, and being middle-school students were significantly associated with spending long periods watching TV and using the computer. Therefore, primary health care providers should record the TV and non-academic computer time of youths when conducting health promotion programs, and educate parents on how to become good and healthy electronic media users.     

Assessing health-related quality of life in adolescents: some psychometric properties of the first Norwegian version of KINDL

The study presented in this paper is part of a larger Norwegian investigation among adolescents, where the overall aim is to develop methods to promote their quality of life (QoL), to discover risk factors or threats to adolescents' well-being, and finally to prevent the negative effects of such factors. An adequate generic health-related quality of life (HR-QoL) measure is therefore needed. However, only a limited number of well validated instruments that measure HR-QoL in adolescents exist, and to date only a few has been translated into Norwegian. The purpose of this study was therefore to examine some psychometric properties of the first Norwegian version of a simple, generic, German HR-QoL questionnaire for adolescents, KINDL. The instrument consists of 24-items, distributed in six subscales, which correspond to six domains of adolescents' HR-QoL. Based on a sample of 239 healthy adolescents, the internal consistency reliability is satisfactory for both the total scale and the subscales of 'Self-esteem and Family', fairly good for the 'Emotional' subscale, but lower for the subscales 'Physical', 'Friends' and 'School'. Factor analyses, which concerns construct validity, yielded interpretable solutions. The factor solutions at item level were interpreted to be in line with the original subscales, while factor analysis at subscale level indicated that a common QoL core is involved. To conclude, the Norwegian version of KINDL appears, in general, to be a psychometrically acceptable method of measuring HR-QoL in healthy adolescents. However, the alpha-values of some of the subscales are not optimal, and these scales should be used with caution in research and profession. Still KINDL-N is considered suitable for screening purposes in the public health area and especially within school-health care.     

Understanding overweight adolescents' beliefs using the theory of planned behaviour

This qualitative inquiry examined adolescents' experiences surrounding their beliefs towards being overweight. The purpose of this qualitative study was to understand behavioural, normative and control beliefs of overweight adolescents regarding losing weight, exercising and eating healthy. Purposive sampling was used to obtain 10 overweight adolescents between the ages of 13 and 19. The theory of planned behaviour was used as a theoretical framework for this study. An interview guide based on the Theory of Planned was used to conduct individual semistructured interviews. Content analysis showed that overweight adolescents exhibited positive attitudes in dealing with their weight status and valued their family's support and guidance in helping control their weight. Although friends were important to facilitate regular exercise, families, particularly mothers, were crucial in addressing healthy eating habits. Understanding the subtleties and complexities of living with childhood overweight might assist health professionals in creating more effective and developmentally sensitive interventions.     

Adolescents' perspectives on addiction: qualitative study

Given that the adolescence period is one of the most crucial stages of development during one's lifetime and adolescents are prone to engage in behaviors which may negatively impact their health, it is very important to have a clear and transparent understanding of adolescents' health needs and problems. A content analysis with a qualitative approach was conducted and 41 healthy adolescents were interviewed. The results of this study revealed the following themes: addiction causes and prevalence; unhealthy friendship and communication and increased rates of cigarette smoking; alcohol and drugs; barriers to and factors in addiction and health; family and addiction. The findings showed worrying attitudes of adolescents to addiction and its prevalence are alarming. It is concluded that exploring adolescents' perspectives is not only important but is useful for maintaining a healthy society, and thus policy makers should develop effective prevention and intervention programs based on these themes.     

Validity and reliability of the Turkish version of the Urinary Catheter Self-Care Management Questionnaire

This research aims to analyse the validity and reliability of the Turkish version of the Urinary Catheter Self-Efficacy Scale (C-SE) and the Urinary Catheter Self-Management Scale (C-SMG), which comprise the Urinary Catheter Self-Care Management Questionnaire. This research is planned as a cross-sectional, methodological type of scale adaptation study. The research was conducted in three hospitals in the northwest of Turkey with 101 patients. Content validity index and confirmatory factor analysis were used in the validity analyses. In the reliability analyses, Cronbach's alpha coefficient, the split-half method, the item-total score, and Pearson's correlation analyses were used. The content validity index was 0.911 for the C-SE and 0.989 for the C-SMG. Cronbach's alpha values for the scales were 0.928 and 0.882, respectively. Besides, the item-total correlations changed between 0.562 and 0.831 for the C-SE and between 0.315 and 0.759 for the C-SMG. The coefficients got in halving were 0.960 and 0.943, respectively. The two scales that make up the Urinary Catheter Self-Care Management Questionnaire are valid and reliable measurement tools that can be used for patients undergoing long-term urinary catheterization in Turkey. In line with the results obtained from this study, we suggest that the Urinary Catheter Self-Care Management Questionnaire should be used to evaluate the self-efficacy or self-management levels of Turkish patients undergoing long-term urinary catheterization and to evaluate the effects of nursing interventions on the self-efficacy or self-management levels of patients who have undergone long-term urinary catheterization.     

Health beliefs and health behaviors of physical therapists

The purpose of this study was to examine the health beliefs and health behaviors of physical therapists. A survey questionnaire was sent to a 10% random sample of the physical therapists on the Texas licensure list for 1984, and 234 responses (69%) were used in the data analysis. The respondents tended to have positive health beliefs and good health behaviors in terms of a healthy life style. These findings have implications for physical therapists as role models for encouraging good health habits in their patients.     

Gender differences in health risk behaviors and physical activity among middle school students.

Adolescence is a period of accelerated growth and change, bridging the complex transition from childhood to adulthood. This period offers adolescents an opportunity to begin planning for their futures and to adopt healthy attitudes about risk behaviors that can continue into adulthood, thus setting the stage for a lifetime of desirable health behaviors. This study used the Youth Risk Behavior Survey on middle school students and examined the gender differences of health risk behaviors among 674 8th-graders from an urban setting. The results showed that males were more likely to be involved in fights, to initiate alcohol use, and to participate in physical activity; whereas females were more likely to try to lose weight with unhealthy practices, such as fasting and laxatives. School nurses are in a prime position to promote adolescent health in the school setting by providing health-related services and teaching to help students initiate and maintain healthy lifestyles.     

Psychometric evaluation of the personal lifestyle questionnaire for adolescents.

The purpose of this study was to provide evidence of validity for the Personal Lifestyle Questionnaire (PLQ), a measure of positive health practices, in a sample of 222 adolescents ages 15-21. Using a priori criteria, it was found that a two-factor solution, resulting from a principal components analysis with an orthogonal rotation, best represented the factor structure of the PLQ for adolescents. Of the two factors, only Factor I demonstrated an acceptable coefficient alpha reliability; this factor was labeled General Health Practices. Evidence of construct validity for the total PLQ was provided by two statistically significant correlations found between the scale and the theoretically relevant variables of perceived health status and symptom patterns. Contrary to expectation, dependency was not related to positive health practices. A post hoc analysis indicated that Factor I correlated significantly with perceived health status and symptom patterns. The results support the use of Factor I, consisting of 13 items, as a measure of general health practices with adolescents.     

Development of an evidence-based practice questionnaire for nurses

AIM: The aim of this paper is to report the development and validation of a self-report measure of knowledge, practice and attitudes towards evidence-based practice (EBP). BACKGROUND: Evidence-based practice has become increasingly important in health care since the mid-1990s as it provides a framework for clinical problem-solving. However, to date no means exist to quantify the extent to which barriers, such as lack of time in the working day, lack of appropriate skills and negative attitudes, may prevent greater uptake of EBP. METHODS: Questionnaire development was based on established psychometric methods. Principal component factor analysis was used to uncover the underlying dimensions of the scale. Internal consistency of the scale was assessed by Cronbach's alpha. Finally, construct validity was assessed via convergent and discriminant validity. RESULTS: The final questionnaire comprised three distinct scales (EBP, attitudes towards EBP and knowledge of EBP), which had robust validity and internal reliability. CONCLUSION: This tool can be used to measure the implementation of EBP.     

Nomology,validity, and interprofessional research: The missing link(s)

ABSTRACT

There are many calls for increased rigor in interprofessional research, and scale validation improvements are particularly needed. Specifically, current validation efforts are limited, as few interprofessional scale development studies report evidence of convergent and discriminant validity. These are core aspects of establishing nomological networks and construct validity, and thus form the foundation of interprofessional theory, research, and practice. This paper focuses on the importance of construct validation for interprofessional measurement tools, reviewing key concepts, extant scales and their validation efforts, and providing recommendations for future interprofessional scale validation. We also provide a step-by-step guide for scale development and validation that we hope will be valuable for future researchers and scale developers in the interprofessional literature.     

Development of a support skill scale in insulin therapy: A nationwide study in Japan

The aim of this cross-sectional, nationwide study in Japan was to develop a support skill scale for insulin therapy (IT-SSS) and to evaluate its validity and reliability. The sample consisted of 1604 nurses at 123 hospitals throughout the country. The factor validity, known-group validity, convergent validity, discriminant validity and internal consistency of IT-SSS were assessed. IT-SSS consisted of 26 minimum and 25 standard support skills. They included 4 subscales for minimum skills: management strategy for hypoglycemia, education about insulin injection technique, individual assessment and support about insulin rejection, and collaboration with medical professionals and patient/family. Three subscales for standard skills: apprehensions concerning the will and emotion of the patient, management for blood glucose control, and coordination in insulin management. Cronbach's alpha coefficient was between 0.75 and 0.90, suggesting strong internal consistency. Multitrait analysis showed that convergent validity was complete, and discriminant validity was found to be almost complete in both minimum and standard skill scales (scaling success rates of 97.6% and 98.7% across all subgroups, respectively). Known group analysis clearly showed that specialist nurses have significantly higher skills than general nurses. These findings indicate that IT-SSS has a reasonable factor validity, convergent validity, discriminant validity, known group validity, and internal consistency.
