Utilization of Infertility Services: How Much Does Money Matter?

Objective. To estimate the effects of financial access and other individual characteristics on the likelihood that a woman pursues infertility treatment and the choice of treatment type.
Data Source/Study Setting. The 1995 National Survey of Family Growth.
Study Design. We use a binomial logit model to estimate the effects of financial access and individual characteristics on the likelihood that a woman pursues infertility treatment. We then use a multinomial logit model to estimate the differential effects of these variables across treatment types.
Data Collection/Extraction Method. This study analyzes the subset of 1,210 women who meet the definition of infertile or subfecund from the 1995 National Survey of Family Growth.
Principal Findings. We find that income, insurance coverage, age, and parity (number of previous births) all significantly affect the probability of seeking infertility treatment; however, the effect of these variables on choice of treatment type varies significantly. Neither income nor insurance influences the probability of seeking advice, a relatively low cost, low yield treatment. At the other end of the spectrum, the choice to pursue assisted reproductive technologies (ARTs)—a much more expensive but potentially more productive option—is highly influenced by income, but merely having private insurance has no significant effect. In the middle of the spectrum are treatment options such as testing, surgery, and medications, for which "financial access" increases their probability of selection.
Conclusions. Our results illustrate that for the sample of infertile of subfecund women of childbearing age studied, and considering their options, financial access to infertility treatment does matter.

Body size categorization in anorexia nervosa using a morphing instrument

OBJECTIVE: To test the feasibility of the technique of "morphing" for body image assessment purposes and to investigate whether females with anorexia nervosa (AN) categorize other female's body sizes similarly to controls. METHOD: A morphing movie showing the transformation of a thin woman into an obese woman was presented. Females with AN and thin controls selected the sizes corresponding to the transitions between the body size categories thin, normal, fat, and obese. They were instructed to look at the woman in the movie as themselves (Self) versus someone else (Other). RESULTS: The AN group chose significantly lower transitions associated with the categories thin, normal, fat, and obese under the Self instruction than controls. Similarly, they selected lower settings for all but the obese category when looking at the body as someone else's. It was concluded that females with AN display a harsher judgment not only of their own body size and shape, but also of that of another woman, than women without an eating disorder. DISCUSSION: The morphing instrument was found to be sufficiently realistic, detailed, and sensitive for its intended purposes.     

Elaboration and validation of instrument to assess adherence to hypertension treatment

OBJECTIVE

To elaborate and validate an instrument of adherence to treatment for systemic arterial hypertension, based on Item Response Theory.

METHODS

The process of developing this instrument involved theoretical, empirical and analytical procedures. The theoretical procedures included defining the construct of adherence to systemic arterial hypertension treatment, identifying areas involved and preparing the instrument. The instrument underwent semantic and conceptual analysis by experts. The empirical procedure involved the application of the instrument to 1,000 users with systemic arterial hypertension treated at a referral center in Fortaleza, CE, Northeastern Brazil, in 2012.. The analytical phase validated the instrument through psychometric analysis and statistical procedures. The Item Response Theory model used in the analysis was the Samejima Gradual Response model.

RESULTS

Twelve of the 23 items of the original instrument were calibrated and remained in the final version. Cronbach’s alpha coefficient (α) was 0.81. Items related to the use of medication when presenting symptoms and the use of fat showed good performance as they were more capable of discriminating individuals who adhered to treatment. To ever stop taking the medication and the consumption of white meat showed less power of discrimination. Items related to physical exercise and routinely following the non-pharmacological treatment had most difficulty to respond. The instrument was more suitable for measuring low adherence to hypertension treatment than high.

CONCLUSIONS

The instrument proved to be an adequate tool to assess adherence to treatment for systemic arterial hypertension since it manages to differentiate individuals with high from those with low adherence. Its use could facilitate the identification and verification of compliance to prescribed therapy, besides allowing the establishment of goals to be achieved.     

Development of an instrument to measure beliefs and attitudes from heart valve disease patients

The objective of this study was to verify content validity and reliability of "CAV-Instrument" -- an instrument to measure beliefs and attitudes of heart valve disease patients concerning their illness and treatment. The instrument was analyzed by three judges (using predetermined criteria) and submitted to the pretest (n = 17 subjects). The majority of the items were evaluated as adequate regarding their pertinence, clearness and significance regarding the analyzed questions. The pretest showed the necessity for small changes in some statements, which optimized instrument comprehension by the patients. The restructured instrument was applied to 46 patients to verify internal consistency. The whole instrument and most of its scales presented satisfactory internal consistency. It is concluded that the instrument has content validity and is internally consistent, ratifying the adequacy of its application to measure the strength of association among the researched variables.

Development of observational methods for estimation of exposure to workplace postural stress

Several recent studies have illustrated the need for a simpleobservational instrument for the estimation of exposure to posturalstress in epidemiological studies of musculoskeletal disorders.Such an instrument is particularly necessary in developing countries.This paper describes the development of an observational instrumentacross a spectrum of industrial occupations in South Africa.The instrument was derived from adaptations to previously publishedobservational methods and was specifically adapted to the measurementand application constraints identified during empirical developmentwork in various industries. The final instrument fulfilled itsaims of being applicable across a broad spectrum of jobs, includinga broad spectrum of exposure variables and being reasonablycost- and time-effective. Some construct validity is indicatedby the fact that two out of the three main exposure variablesof interest showed significant associations with neck and shoulderpain in an epidemiological analysis. These variables were thescore of summed estimates of the duration of time in sustainedpostures in a working day and the score of estimated overallrepetitiveness based on cycle-time criteria. Further investigationsare needed for pain at other anatomical sites. The measurementand scoring problems identified are discussed with referenceto some aspects of these results.
