Study Overview

Brief Summary

Stuttering is a common fluency disorder characterized by involuntary interruptions in speech flow, such as repetitions, prolongations, and blocks. It affects approximately 1% of the world's population and typically emerges in the early stages of language development, particularly in preschool. The exact cause of stuttering is still unknown, but it is believed to involve various combinations of genetic, developmental, environmental, and neurophysiological factors (Yairi and Ambrose, 2013). Stuttering not only affects an individual's communication skills but can also significantly impact their psychological and emotional state. Individuals may experience persistent anxiety about being ridiculed or negatively evaluated by others during stuttering episodes, and the pressure to speak fluently in everyday situations can create significant stress and anxiety (Guitar, 2013). The ICF model, developed by the World Health Organization, suggests examining an individual's health status not only at the biological level but also in the context of activity, participation, and environmental factors (WHO, 2001). In particular, the ICF-based model proposed by J. Scott Yaruss and Robert W. Quesal for stuttering offers an important framework for explaining the impact of stuttering on an individual's quality of life. In this context, stuttering is characterized by limited participation in social and professional life in terms of the level of participation (Yaruss & Quesal, 2004). Individuals with stuttering may experience a number of problems in their professional lives. Job interviews can be given as an example of these situations. Job interviews are an important starting point in the employment process. Job interviews are a situation that creates anxiety and causes avoidance behaviors for individuals with stuttering (Hohulin et al., 2010). Anxiety is defined as "unease, irrational fear, anxiety, worry, distress caused by an unknown danger, misfortune, fear or expectation originating from the unconscious" (Bakırcıoğlu, 2016: 893). When adult individuals with stuttering are faced with a socially threatening, anxiety-inducing environment, they show physical strain and their anxiety increases during stuttering (Bloodstein, 1995; Craig, 2003). The literature reports a positive correlation between threatening or challenging stimuli and the severity of stuttering. For example; Stuttering is observed to increase when speaking to an authority figure, a group, or impatient or critical listeners (Guitar, 2013). Conversely, the frequency of stuttering generally decreases in non-anxiety-inducing situations, such as speaking to a familiar person or someone who is not an authority figure (Craig, 2006). Furthermore, speakers with severe stuttering are more likely to be subjected to negative evaluations and labeling/stigmatization compared to speakers with less severe stuttering (Gabel, 2006). The fear of negative evaluation is defined by Leary (1983) as the individual being evaluated negatively and hostilely by others, or being stigmatized. Stigmatization, in turn, is described as a multidimensional phenomenon encompassing negative attitudes and behaviors towards individuals (Corrigan & Watson, 2002). The literature includes various therapies for stuttering and the accompanying negative emotional states. One of these approaches is known as desensitization. Desensitization for stuttering is considered an important component of therapy for individuals who stutter. According to most research findings in foreign literature, individuals with stuttering perceive job interviews as a difficult area (Bricker-Katz, Lincoln, and Cumming, 2013; Klein and Hood, 2004; Rice and Kroll, 2006). Furthermore, while many studies focus on the working lives of individuals with stuttering, there are only a few studies specifically addressing job search processes and interviews. No studies addressing job interviews for individuals with stuttering have been found in the local literature. Due to this gap in the literature, our research aims to contribute to the literature and guide future studies in this area. Our study will develop a 10-week desensitization-based therapy program and aims to examine the effects of this structured program on stuttering frequency, fear of negative evaluation, internalized stigma, and anxiety experienced during interviews for individuals with stuttering.

Detailed Description

The structured therapy program designed for job interviews is planned for a total of 10 weeks, with pre-tests administered in the first week and post-tests in the last week. (Pre-test measurements will be taken in the 1st week, and post-test measurements in the 10th week.) Data collection will be conducted by the researcher through 40-50 minute individual therapy sessions once a week. Participants who approve the Informed Consent Form (Appendix 8) will be included in the study. Pre-test and post-test measurements will be collected via Google Forms, and the intervention program will be conducted face-to-face in the office in the 8th week, while the other weeks will be conducted online, in a hybrid format. A pilot application will be conducted before the main study begins. Job interviews in the 7th and 8th weeks will be conducted by an expert experienced in job interviews. After the intervention group completes the process, an accelerated program will be applied to the control group. While developing the content of the therapy, the literature was reviewed and desensitization-focused programs were examined (Hohulin and Sawyer, 2010; Çağlayan, 2024). Care was taken to ensure a systematic hierarchical structure in the development of the intervention, and the therapy content included desensitization strategies; education, voluntary stuttering, self-disclosure statements, gradual exposure, cognitive restructuring, scenario-based work, and role-playing exercises.

The program was finalized after obtaining expert opinions from 5 faculty members specializing in stuttering with at least 5 years of experience. The weekly general content plans for the therapies are presented below. WEEK 1:

- Taking pre-tests (via Google Forms) and providing information about the therapy process.

  • Demographic Information Form
  • Stuttering Frequency Measurement (400-syllable speech video recording sample)
  • Internalized Stigma Scale
  • Fear of Negative Evaluation Scale
  • Interview Anxiety Scale
  • Beck Depression Scale (The individual will complete the Beck Depression Scale for exclusion criteria.)
  • Beck Anxiety Scale (The individual will complete the Beck Anxiety Scale for exclusion criteria.)

Outcomes

Primary Outcomes

Stuttering frequency

Time Frame: Baseline (Week 0) and Week 10

Change in stuttering frequency calculated from standardized speech samples.

ANXIETY IN SELECTION INTERVIEWS

Time Frame: Baseline (Week 0) and immediately after completion of the 10-week intervention (Week 10)

MEASURE OF ANXIETY IN SELECTION INTERVIEWS (MASI)

fear of negative evaluation

Time Frame: Baseline (Week 0) and immediately after completion of the 10-week intervention (Week 10)

Change in fear of negative evaluation measured using the Brief Fear of Negative Evaluation Scale (BFNE). Higher scores indicate greater fear of negative evaluation.

self-stigma

Time Frame: Baseline (Week 0) and immediately after completion of the 10-week intervention (Week 10)

Change in self-stigma related to stuttering measured using the Self-Stigma of Stuttering Scale (4S-TR). Higher scores indicate greater self-stigma.

Secondary Outcomes

No secondary outcomes reported
