Improving the Validity and Reliability of a Health Promotion Survey for Physical Therapists

Purpose

Physical therapists (PTs) have a unique opportunity to intervene in the area of health promotion. However, no instrument has been validated to measure PTs’ views on health promotion in physical therapy practice. The purpose of this study was to evaluate the content validity and test-retest reliability of a health promotion survey designed for PTs.

Methods

An expert panel of PTs assessed the content validity of “The Role of Health Promotion in Physical Therapy Survey” and provided suggestions for revision. Item content validity was assessed using the content validity ratio (CVR) as well as the modified kappa statistic. Therapists then participated in the test-retest reliability assessment of the revised health promotion survey, which was assessed using a weighted kappa statistic.

Results

Based on feedback from the expert panelists, significant revisions were made to the original survey. The expert panel reached at least a majority consensus agreement for all items in the revised survey and the survey-CVR improved from 0.44 to 0.66. Only one item on the revised survey had substantial test-retest agreement, with 55% of the items having moderate agreement and 43% poor agreement.

Conclusions

All items on the revised health promotion survey demonstrated at least fair validity, but few items had reasonable test-retest reliability. Further modifications should be made to strengthen the validity and improve the reliability of this survey.Key Words: health promotion, physical therapy, validity, reliability

Barriers in school-to-community transition.

Effective planning to resolve the school-to-community transition problems of hearing-impaired youth begins with an understanding of what the specific problems are. To identify obstacles to successful transition, survey forms were developed for three groups--the deaf, hard-of-hearing, and deaf multihandicapped--and distributed in the Pacific Northwest to educators, rehabilitation specialists, parents, and hearing-impaired youth. The respondents to the survey of deaf youth varied in their perceptions of the most significant barriers to successful transition. The majority of the top-ranked barriers were related to educational preparation and experiences. The ratings among the four groups responding to the survey of hard-of-hearing youth were more homogeneous. The major barriers identified centered on communication issues and a lack of adequate role models. The respondents to the multihandicapped survey agreed strongly that many problems create obstacles for this group and that problems appear to occur with a higher frequency for deaf multihandicapped persons than for deaf and hard-of-hearing persons.     

Reading aloud: A way for parents to support their children's growth in literacy

Parents can form a vital link to literacy and later school success by encouraging literacy and language modeling in their daily communication with children. This article describes a study in Head Start classrooms in Florida and North Carolina where teachers used a book lending system and high quality books which they shared with children and families. Strategies for teachers to assist parents in providing support for emergent literacy are given. Ways to help families see the importance of their practices and encourage the use of these ideas as part of their daily routines are shared.     

Spelling and grammar checkers: are they intrusive?

Spelling and grammar checkers help to make surface errors more apparent; do they influence the way in which people revise the content of their writing? We investigated whether the presence of checkers distracts students from making content revisions. Twenty‐five freshmen, 20 English majors and 20 graduate students revised two essays on a computer, one with the spelling and grammar checkers, and the other with a dictionary. These essays were unfamiliar to the students and rigged with content and surface errors. The checkers helped the participants to revise text for surface features but did not affect the students’ other revisions. Our findings suggest that checkers are helpful yet do not inhibit students’ ability to make content revisions.

Organizational and Intercultural Communication: An Annotated Bibliography

Professional technical communication often takes place within a larger organizational structure, a structure defined and constrained by both external (national or disciplinary) and internal (organizational) cultures. Thus, theories that help technical communicators analyze and understand organizations can be of especial importance. This bibliography overviews theories of organization from the viewpoint of culture, using five themes of organizational research as a framework. Based on this framework, each section introduces specific theories of international, intercultural, or organizational communication, building upon them through a series of related articles, and showing how they can be applied in the field of technical communication.     

An investigation of proportional time spent in various communication activities by college students

This article examines ethics of consultants from the perspective of counter‐rational organizational theory. First, a set of four ethical questions, derived from Kohlberg, are presented. Second, a real consulting scenario is described, and the author's intervention is outlined. Finally, the implications of the case to consulting practice are discussed.
