Dyspnea And Outcome Expectations Are Associated With Physical Activity In Persons With Pneumoconiosis: A Cross-Sectional Study

Background: There are various reports on factors associated with physical activity in patients with chronic respiratory diseases. However, there are no studies on the relationship between physical activity and psychological or environmental factors. In this study, we investigated the relationship between physical activity and psychological and environmental factors using questionnaires for patients with pneumoconiosis.Methods: The present study was a cross-sectional study of patients with pneumoconiosis who underwent pneumoconiosis health examination in 2019. A self-administered questionnaire was used to conduct the study. Physical activity was evaluated using the International Physical Activity Questionnaire, and subjective symptoms (dyspnea and quality of life [QOL]), environmental factors (environment around home and life space), psychological factors (depression, stage of change, self-efficacy, decisional balance, and outcome expectations), and others (e.g., experience with pulmonary rehabilitation) were investigated.Results: The number of respondents in the study was 185 (men: 171, women: 14). Age, dyspnea, stage of change, self-efficacy, outcome expectations, QOL, depression, decisional balance, and life space were significantly correlated with physical activity. In the multivariate analysis, outcome expectations and dyspnea were extracted as independent factors. In the path analysis, outcome expectations and dyspnea had a direct influence on physical activity. Dyspnea directly impacted not only physical activity but also outcome expectations, stage of change, QOL, life space, and depression.Conclusions: Dyspnea and outcome expectations were associated with physical activity in patients with pneumoconiosis. To improve the physical activity of patients with pneumoconiosis, it is necessary not only to improve dyspnea but also to promote an understanding of physical activity.

Intervention for promoting intake of fruits and vegetables in Brazilians: a randomised controlled trial

Objective: To evaluate the effectiveness of a nutritional intervention to promote fruit and vegetable (FV) intake. Design: A randomised controlled community trial was conducted to evaluate the effectiveness of a 7-month nutritional intervention and to promote FV intake, separately and together. All participants attended physical exercise sessions. The intervention was based on the transtheoretical model and Paulo Freire’s pedagogy. The interventions included group educational sessions, motivational cards and informational materials. The primary outcome was a change in FV intake (g/d), and secondary outcomes included stages of change, self-efficacy, decisional balance and knowledge on FV. All data were collected face-to-face; and FV intake was assessed using a validated brief questionnaire. Setting: Health promotion services of Brazilian Primary Health Care. Participants: 3414 users of Brazilian Primary Health Care (1931 in the control group and 1483 in the intervention group (IG)). Results: At baseline, the average daily FV intake was 370·4 g/d (95 % CI 364·2, 376·6). The increase in FV intake (23·4 g/d; 95 % CI 6·7, 40·0) and fruit intake (+17·3 g/d; 95 % CI 5·1, 29·4; P = 0·01) was greater in the IG among participants in the lowest baseline intake. Participants in the IG also showed progression in the stages of change (P < 0·001), increased self-efficacy (P < 0·001) and improved knowledge of FV crops (P < 0·001). Conclusions: The nutritional intervention was effective in increasing FV intake and fruits intake among individuals with a lower intake at baseline and in maintaining FV intake among those who reported consuming FV as recommended (400 g/d).

Applying the Transtheoretical Model to Stuttering Management Among Adolescents: Part II. Exploratory Scale Validation

Purpose This article is the second in a two-part series on the application of the Transtheoretical Model to stuttering management among adolescents. The purpose of this article was to apply and explore the validity of newly developed Transtheoretical measures for adolescents who stutter. Method The online survey was completed by a national sample of 173 adolescents who stutter between the ages of 13 and 21 years. The multipart survey included a Stage of Change scale, Decisional Balance scale, and Situational Self-Efficacy scale. Participants also completed the Overall Assessment of the Speaker's Experience of Stuttering (OASES), either the teenage or adult version depending on the participant's age, so preliminary construct validity of the new scales could be examined. Exploratory factor analyses were conducted to determine model fit and reduce the scales to the most meaningful items. External validity of the three-part survey was examined by comparing OASES scores across stage of change as well as evaluating the functional relations between the three scales. Results Adolescents' readiness to manage stuttering could be clearly described with five discrete stages, although most of the respondents reported being in the Maintenance stage. The pros of managing stuttering reliably predicted stage placement. Internal consistency of the scales ranged from good to excellent. OASES scores differed across stages of readiness in complex but predictable ways. Conclusions These findings suggest that the Transtheoretical Model fits the target behaviors involved stuttering management among adolescents. Further examination of the application of the model to validate a stage-based framework for change among individuals who stutter is warranted.

Cross-cultural validation of the decisional balance scale in exercise across countries

Background This study examined the psychometric properties of the Korean and Malay version of the decisional balance (DB) for exercise (i.e. perceived benefits and perceived barriers) using a cross-sectional design. Also, this study assessed the measurement and structural invariance of the DB scale across countries. Methods A cross sectional study was conducted in Malaysia and Korea. The study sample consisted of 574 Korean participants and 562 Malaysian participants. The mean age of the participants was 19.8 (SD = 1.29) for the Korean sample and 19.8 (SD = 1.22) for the Malaysian sample. Participants were invited to complete the DB scale with the 10-item and two factors (i.e., perceived benefit and perceived barriers). Confirmatory factor analysis (CFA) and invariance test were conducted on the data by using Mplus 8.3. Results The CFA results based on the hypothesised measurement model of two factors and ten items showed sufficient construct validity after adding residual covariance between items within the same factor: CFI = 0.979, TLI = 0.970, SRMR = 0.036, RMSEA = 0.036 for the Korea sample, and CFI = 0.964, TLI = 0.949, SRMR = 0.055, RMSEA = 0.066 for the Malay sample. For the Korea sample, the construct reliability was 0.62 and 0.74 for perceived benefits and perceived barriers respectively. For the Malay sample, the construct reliability was 0.75 and 0.77 for perceived benefits and perceived barriers respectively. The findings presented evidence for measurement and structural invariance of the DB scale for the Korea and Malaysia samples. Conclusion The DB scale was a valid and reliable measure for assessing exercise behaviour and for making comparisons between Korean and Malaysian samples.

Physical Activity Engagement outside of College Physical Education: Application of the Transtheoretical Model

Objective: In this study, we examined physical activity (PA) engagement outside of college physical education (PE) classes using the Transtheoretical Model (TTM). Methods: Overall, 414 university students enrolled in PE classes voluntarily participated in this study. Participants were asked to complete a survey packet to measure 4 core constructs of TTM and their PA level performed outside of PE classes. Among the participants, 150 randomly selected students were asked to wear a triaxial accelerometer for 7 consecutive days to identify their PA level. Descriptive statistics and multivariate analyses of variance were used to determine the association between stages of motivational readiness and other strategic core constructions. Results: We categorized 77% of respondents into either the "action" stage or the "maintenance" stage for engaging in additional PA outside of the classes. Behavioral processes of change showed a graded and significant association with the stages. Both self-efficacy and decisional balance were significantly higher in students at higher stages. Conclusion: Our findings showed that most students enrolled in college PE classes had additional PA outside of the class participation. In addition, behavioral processes may be effective strategies for this specific target group to promote PA.

Applying the Transtheoretical Model to Stuttering Management Among Adolescents: Part I. Scale Development

Purpose This article is the first in a two-part series on the application of the Transtheoretical Model to stuttering management among adolescents. In this article, we describe the process of developing measures to assess stage of change (SOC) by defining behaviors of stuttering management, as well as the two primary cognitive constructs that underlie one's readiness to make behavioral change: decisional balance (DB) and situational self-efficacy (SSE). This work hinges on the ability to develop an operational definition of what it means to successfully manage or do something positive about one's stuttering. Method We used an iterative process to develop the three scales. Through qualitative analysis of key informant interview and focus group transcripts with 24 adolescents who stutter and 26 clinicians specializing in stuttering, we developed stuttering-specific SOC, DB, and SSE scales. The drafted scales were cognitively tested with nine adolescents who stutter. Results Thematic analysis yielded a three-part definition of successful stuttering management that formed the basis for the SOC scale: (a) learning and using strategies to modify speech or stuttering, (b) changing negative thoughts and attitudes regarding stuttering, and (c) talking without avoiding sounds, words, or situations. Results from this analysis support a broader view of successful stuttering management; that is, it is likely that doing so requires more than just behavior change, which has long been considered the main objective of stuttering treatment. Additional analyses yielded pros and cons of managing stuttering (62 items for the DB scale) and situations in which it is difficult to manage stuttering (39 items for the SSE scale). Conclusions Qualitative analyses provided a three-part definition of “stuttering management” and a comprehensive pool of items that would allow measurement of DB and SSE that underlie readiness to manage stuttering among adolescents. In the companion article in this two-part series, we describe the next step in scale development: exploratory scale validation of the drafted SOC, DB, and SSE scales.

Effects of Brain Breaks Video Intervention of Decisional Balance among Malaysians with Type 2 Diabetes Mellitus: A Randomised Controlled Trial

Brain Breaks® are structured physical activity (PA) web-based videos designed to promote an interest in learning and health promotion. The objective of this study was to examine its effects on decision balance (DB) which consists of the perceived benefits (Pros) and perceived barriers (Cons) of exercise in people with type 2 diabetes mellitus (T2DM). A randomised controlled trial was conducted among people with T2DM at Hospital Universiti Sains Malaysia. The intervention group received Brain Breaks videos for a period of four months. The intervention and control groups completed the validated Malay version of DB questionnaire for five times, at pre-intervention, the first month, the second month, the third month, and post-intervention. Multivariate Repeated Measures Analysis of Variance was performed for data analysis. A total of 70 participants were included (male = 39; female = 31) with a mean age of 57.6 years (SD = 8.5). The intervention group showed a significant change in the Pros and Cons factors of DB scores over time. The intervention group showed significantly higher scores for the Pros (p-value < 0.001) and lower scores for the Cons (p-value = 0.008) factors than the control group. In conclusion, the Brain Breaks video is an effective intervention to improve decisional balance in patients with T2DM to help them in deciding on behaviour change to be more physically active.
