Is the Scale for Measuring Motivational Interviewing Skills a valid and reliable instrument for measuring the primary care professionals motivational skills?: EVEM study protocol.

ABSTRACT: Lifestyle is one of the main determinants of people's health. It is essential to find the most effective prevention strategies to be used to encourage behavioral changes in their patients. Many theories are available that explain change or adherence to specific health behaviors in subjects. In this sense the named Motivational Interviewing has increasingly gained relevance. Few well-validated instruments are available for measuring doctors' communication skills, and more specifically the Motivational Interviewing.The hypothesis of this study is that the Scale for Measuring Motivational Interviewing Skills (EVEM questionnaire) is a valid and reliable instrument for measuring the primary care professionals skills to get behavior change in patients. To test the hypothesis we have designed a prospective, observational, multi-center study to validate a measuring instrument. -Thirty-two primary care centers in Spain. -Sampling and Size: a) face and consensual validity: A group composed of 15 experts in Motivational Interviewing. b) Assessment of the psychometric properties of the scale; 50 physician- patient encounters will be videoed; a total of 162 interviews will be conducted with six standardized patients, and another 200 interviews will be conducted with 50 real patients (n=362). Four physicians will be specially trained to assess 30 interviews randomly selected to test the scale reproducibility. -Measurements for to test the hypothesis: a) Face validity: development of a draft questionnaire based on a theoretical model, by using Delphi-type methodology with experts. b) Scale psychometric properties: intraobservers will evaluate video recorded interviews: content-scalability validity (Exploratory Factor Analysis), internal consistency (Cronbach alpha), intra-/inter-observer reliability (Kappa index, intraclass correlation coefficient, Bland & Altman methodology), generalizability, construct validity and sensitivity to change (Pearson product-moment correlation coefficient).The verification of the hypothesis that EVEM is a valid and reliable tool for assessing motivational interviewing would be a major breakthrough in the current theoretical and practical knowledge, as it could be used to assess if the providers put into practice a patient centered communication style and can be used both for training or researching purposes.

Project description:BackgroundPeople's sexual experiences have a strong association with contraceptive satisfaction and continuation, but no measures exist to specifically assess contraceptive-related sexual acceptability.AimThis study developed and examined the psychometric properties of reliability, separation, and item fit of a new Contraceptive Sexual Acceptability (CSA) instrument.MethodsEnrolled participants initiating a new contraceptive method from the HER Salt Lake longitudinal cohort study contributed baseline survey responses for scale development. The study included the Female Sexual Function Index, the New Sexual Satisfaction Scale, measures of physical and mood-related side effects, and self-reported perceptions of contraception's sexual impacts. Items from these measures' served as the basis for analyses. We analyzed responses using descriptive techniques and modeled using exploratory factor (EFA) and bifactor analyses (BFA). The Masters' Partial Credit Rasch method modeled reliability, separation, and item fit statistics. Here we evaluate (i) the reproducibility of relative measure location on the modeled linear latent variable, (ii) the number of statistically unique performance levels that can be distinguished by the measure, and (iii) the discrepancy between item responses and expectations of the model. Psychometric findings and theoretical models informed item reduction and final scale development.OutcomesWe developed a 10-item Contraceptive Sexual Acceptability scale that exceeded the thresholds and sufficiently covered domains for use in contraceptive research and clinical settings.ResultsStarting with data on 39-items from 4,387 individuals, we identified 10-items that best measured the CSA latent construct. The Rasch model included a total of 5 calibrations. We reduced items based on bifactor analysis and surpassed unidimensionality thresholds (OH = 0.84, ECV = 0.74) set a priori. The final items included questions with scaled responses about pleasure and orgasm (orgasm quality, orgasm frequency, giving partner pleasure), physical (arousal and function) and psychological (emotional connection, surrender) components, general questions of satisfaction and frequency, and a measure of perceived impact of contraception on sexual experiences in the previous 4 weeks.Clinical implicationsThe 10-item CSA instrument covers physical and psychological aspects of contraceptive sexual acceptability and can be used in clinical settings.Strengths & limitationsThe unidimensional CSA instrument offers a brief, yet comprehensive assessment of sexual acceptability. Given the limited diversity of the sample, implementation of this scale in contraceptive research and clinical interactions should be evaluated and validated in more diverse settings.ConclusionAttuning to sexual acceptability could ultimately help contraceptive clients find methods that better meet their needs and preferences.

Project description:BackgroundThe technical hypothesis of Motivational Interviewing (MI) proposes that: (a) client talk favoring behavior change, or Change Talk (CT) is associated with better behavior change outcomes, whereas client talk against change, or Sustain Talk (ST) is associated with less favorable outcomes, and (b) specific therapist verbal behaviors influence whether client CT or ST occurs. MI consistent (MICO) therapist behaviors are hypothesized to be positively associated with more client CT and MI inconsistent (MIIN) behaviors with more ST. Previous studies typically examine session-level frequency counts or immediate lag sequential associations between these variables. However, research has found that the strongest determinant of CT or ST is the client's previous CT or ST statement. Therefore, the objective of this paper was to examine the association between therapist MI skills and subsequent client talk, while accounting for prior client talk.MethodsWe analyzed data from a manualized MI intervention targeting both alcohol misuse and sexual risk behavior in 132 adults seen in two hospital emergency departments. Transcripts of encounters were coded using the Motivational Interviewing Skills Code (MISC 2.5) and an additional measure, the Generalized Behavioral Intervention Analysis System (GBIAS). Using these measures, we analyzed the association between client talk following specific classifications of MICO skills, with the client's prior statement as a potential confounder or effect modifier.ResultsWith closed questions as the reference category, therapist simple reflections and paraphrasing reflections were associated with significantly greater odds of maintaining client talk as CT or ST. Open questions and complex reflections were associated with significantly greater odds of CT following ST, were not associated significantly with more ST following ST, and were associated with more ST following CT (i.e., through an association with less Follow Neutral).ConclusionsSimple and paraphrasing reflections appear to maintain client CT but are not associated with transitioning client ST to CT. By contrast, complex reflections and open questions appeared to be more strongly associated with clients moving from ST to CT than other techniques. These results suggest that counselors may differentially employ certain MICO technical skills to elicit continued CT and move participants toward ST within the MI dialogue.

Project description:Veterinarians often give advice in a persuasive form, a style that has been shown to evoke resistance to change in clients experiencing psychological ambivalence (i.e. those who see both advantages and disadvantages to changing). With this style of communication, veterinarians run the risk of counteracting their purpose to encourage clients to follow recommendations. Motivational interviewing (MI) is a client-centered communication methodology that aims to facilitate clients' internal motivation to change. In MI, Change Talk represents clients' own statements expressing consideration of, motivation for or commitment to behavior change and has been shown to be strongly correlated with behavior change. Sustain Talk is corresponding statements related to maintaining the status quo. The aim of this exploratory study was to evaluate the potential of MI to facilitate behavior change in veterinary herd health management (VHHM) by investigating the effect of dairy cattle veterinarians' MI skills on client Change and Sustain Talk. We recorded VHHM consultancies on 170 Swedish cattle farms performed by 36 veterinarians, randomly distributed into 2 groups: MI veterinarians (n = 18) had received 6-month training in MI and control veterinarians (n = 18) had not received any training. Veterinarians' MI skills were assessed using the Motivational Interviewing Treatment Integrity coding system 4.2.1 and categorized as poor_untrained, poor_trained, near moderate and moderate. Client communication was coded using the Client Language Easy Rating coding system. The effect of MI skills on Change Talk, Sustain Talk and Proportion of Change Talk(Change Talk divided by the sum of Sustain Talk plus Change Talk) was investigated using cross-classified regression models with random intercepts for veterinarian and client (farm). The models also included additional explanatory variables (e.g. type of veterinarian and client's satisfaction with the consultation). The veterinarian's MI skills were associated with the client's Change Talk, but results regarding Sustain Talk or Proportion of Change Talk were inconclusive. Clients of veterinarians reaching the highest (i.e. moderate) MI skills expressed 1.5 times more Change Talk than clients of untrained veterinarians. Clients of general large animal practitioners expressed less Sustain Talk than clients of animal health veterinarians and had higher Proportion of Change Talk. Results indicate that learning to practice MI may be one means to improve adherence to veterinary recommendations and to improve efficiency in VHHM services.
