A country-wide probability sample of public attitudes toward stuttering in Portugal

BackgroundNegative public attitudes toward stuttering have been widely reported, although differences among countries and regions exist. Clear reasons for these differences remain obscure.PurposePublished research is unavailable on public attitudes toward stuttering in Portugal as well as a representative sample that explores stuttering attitudes in an entire country. This study sought to (a) determine the feasibility of a country-wide probability sampling scheme to measure public stuttering attitudes in Portugal using a standard instrument (the Public Opinion Survey of Human Attributes–Stuttering [POSHA–S]) and (b) identify demographic variables that predict Portuguese attitudes.MethodsThe POSHA–S was translated to European Portuguese through a five-step process. Thereafter, a local administrative office-based, three-stage, cluster, probability sampling scheme was carried out to obtain 311 adult respondents who filled out the questionnaire.ResultsThe Portuguese population held stuttering attitudes that were generally within the average range of those observed from numerous previous POSHA–S samples. Demographic variables that predicted more versus less positive stuttering attitudes were respondents’ age, region of the country, years of school completed, working situation, and number of languages spoken. Non-predicting variables were respondents’ sex, marital status, and parental status.ConclusionA local administrative office-based, probability sampling scheme generated a respondent profile similar to census data and indicated that Portuguese attitudes are generally typical.     

Public attitudes toward stuttering in Turkey: probability versus convenience sampling

Purpose: A Turkish translation of the Public Opinion Survey of Human Attributes-Stuttering (POSHA-S) was used to compare probability versus convenience sampling to measure public attitudes toward stuttering. Method: A convenience sample of adults in Eski?ehir, Turkey was compared with two replicates of a school-based, probability cluster sampling scheme. Results: The two replicates of the probability sampling scheme yielded similar demographic samples, both of which were different from the convenience sample. Components of subscores on the POSHA-S were significantly different in more than half of the comparisons between convenience and probability samples, indicating important differences in public attitudes. Conclusions. If POSHA-S users intend to generalize to specific geographic areas, results of this study indicate that probability sampling is a better research strategy than convenience sampling.Educational objectives: The reader will be able to: (1) discuss the difference between convenience sampling and probability sampling; (2) describe a school-based probability sampling scheme; and (3) describe differences in POSHA-S results from convenience sampling versus probability sampling.     

Origins of the stuttering stereotype: stereotype formation through anchoring-adjustment

The stereotype of people who stutter is predominantly negative, holding that stutterers are excessively nervous, anxious, and reserved. The anchoring–adjustment hypothesis suggests that the stereotype of stuttering arises from a process of first anchoring the stereotype in personal feelings during times of normal speech disfluency, and then adjusting based on a rapid heuristic judgment. The current research sought to test this hypothesis, elaborating on previous research by [White, P. A., & Collins, S. R. (1984). Stereotype formation by inference: A possible explanation for the “stutterer” stereotype. Journal of Speech and Hearing Research, 27, 567–570]. Participants provided ratings of a hypothetical typical person who stutters, a person suffering from normal speech disfluency and a typical male on a 25-item semantic differential scale. Results showed a stereotype of people who stutter similar to that found in previous research. The pattern of results is consistent with the anchoring–adjustment hypothesis. Ratings of a male stutterer are very similar to a male experiencing temporary disfluency, both of which differ from ratings of a typical male. As expected, ratings of a stutterer show a small but statistically significant adjustment on several traits that makes the stereotype of stutterers less negative and less emotionally extreme than the temporarily disfluent male. Based on the results of this research, it appears that stereotype formation is a result of generalization and adjustment from personal experience during normal speech disfluency.

Educational objectives: The reader will be able to: (1) explain how the negative stereotype of people who stutter arises; (2) discuss the negative implications of stereotypes in the lives of people who stutter; and (3) summarize why the stereotype of people who stutter is so consistent and resistant to change.     

Teacher attitudes toward stuttering

Attitudes of 100 elementary school teachers toward stuttering were studied using the Teacher Attitudes Toward Stuttering (TATS) Inventory. Teacher attitudes, as indicated by TATS Inventory scores, were compared with teacher knowledge of stuttering, age of teacher, number of years teaching experience, educational level, and whether the teacher had personal experience with a stutterer. Results indicated that significant positive correlations existed between teacher attitudes toward and knowledge of stuttering. Significant negative correlations were demonstrated between teacher attitudes/knowledge of stuttering and the presence of a stuttering child in the classroom. The applicability of the TATS Inventory as a clinical instrument in its current form and the research needed to enhance its flexibility are discussed.     

The social and communication impact of stuttering on adolescents and their families

Purpose

Stuttering can cause wide ranging psychosocial impact. This is particularly the case for adolescents who may face additional physical, emotional and personality changes as they become adults. This study reports the findings of an investigation into the social and communication impacts of stuttering on Australian adolescents seeking treatment for stuttering and their families.

Method

A cross-sectional design utilising questionnaires assessed the self-perceived communication competence and apprehension, stigma and disclosure, and experiences of teasing and bullying of 36 adolescents who stutter. Additionally, the impact of stuttering on the families of these adolescents was investigated.

Results

Adolescents who stutter have below average self-perceived communication competence, heightened communication apprehension, are teased and bullied more often than fluent peers, and they try to keep their stuttering secret. The families of the adolescents in the study reported high levels of emotional strain, family conflict and difficulty managing their child's frustrations.

Conclusion

The findings from this study emphasise the wide-ranging impact of stuttering beyond the surface level behaviours. Clinicians working with adolescents who stutter should take note of both the outcomes of this study and the suggestions for more effectively coping with the condition in this population.Educational objectives: The reader will be able to: (a) summarise findings with regards to the impact of stuttering on an adolescent's social and communication skills; (b) summarise areas of impact on the families of adolescents who stutter; (c) compare these findings with previous reported data for this population; (d) discuss the clinical implications of the results for working with adolescents who stutter and their families.     

The accuracy with which adults who do not stutter predict stuttering-related communication attitudes

The purpose of this study was to examine the extent to which adults who do not stutter can predict communication-related attitudes of adults who do stutter. 40 participants (mean age of 22.5 years) evaluated speech samples from an adult with mild stuttering and an adult with severe stuttering via audio-only (n = 20) or audio-visual (n = 20) modes to predict how the adults had responded on the S24 scale of communication attitudes. Participants correctly predicted which speaker had the more favorable S24 score, and the predicted scores were significantly different between the severity conditions. Across the four subgroups, predicted S24 scores differed from actual scores by 4–9 points. Predicted values were greater than the actual values for 3 of 4 subgroups, but still relatively positive in relation to the S24 norm sample. Stimulus presentation mode interacted with stuttering severity to affect prediction accuracy. The participants predicted the speakers’ negative self-attributions more accurately than their positive self-attributions. Findings suggest that adults who do not stutter estimate the communication-related attitudes of specific adults who stutter in a manner that is generally accurate, though, in some conditions, somewhat less favorable than the speaker's actual ratings. At a group level, adults who do not stutter demonstrate the ability to discern minimal versus average levels of attitudinal impact for speakers who stutter. The participants’ complex prediction patterns are discussed in relation to stereotype accuracy and classic views of negative stereotyping.Educational objectives: The reader will be able to (a) summarize main findings on research related to listeners’ attitudes toward people who stutter, (b) describe the extent to which people who do not stutter can predict the communication attitudes of people who do stutter; and (c) discuss how findings from the present study relate to previous findings on stereotypes about people who stutter.     

Defining stuttering for research purposes

This is a response to a Letter to the Editor entitled “Stuttering prevalence, incidence and recovery rates depend on how we define it: Comment on Yairi & Ambrose’ article Epidemiology of Stuttering: 21st Century advances” by Paul Brocklehurst (2013). The criticism was directed specifically toward Yairi and Ambrose’ conclusions, based on review of recent studies, regarding the incidence and prevalence of stuttering. In this response, Brocklehurst's arguments and suggestions of criteria for incidence research are discussed and negated.     

The association of attitudes toward stuttering with selected variables

The Stuttering Inventory, designed to assess knowledge about and identify attitudes toward stuttering was completed by 203 subjects. The relative contributions of age, gender, years of education, knowledge about stuttering, number of people who stutter personally known, number of stuttering courses completed, and possession of the Certificate of Clinical Competence in speech-language pathology towards the prediction of attitudes toward people who stutter, their parents, and the efficacy of therapy were examined. Possessing the Certificate of Clinical Competence was the most reliable predictor of attitude scores. The limitations of this study and related research efforts using paper and pencil assessments of attitudes toward stuttering are discussed.     

“Math is Hard!” The effect of gender priming on women’s attitudes

In three studies, we examined the effect of a self-relevant category prime on women’s attitudes towards the gender-stereotyped domains of arts (positively stereotyped) and mathematics (negatively stereotyped). In Study 1, women who were subtly reminded of the category female (Study 1a) or their gender identity (Study 1b) expressed more stereotype consistent attitudes towards the academic domains of mathematics and the arts than participants in control conditions. In Study 2, women who were reminded of their female identity similarly demonstrated a stereotype-consistent shift in their implicit attitudes towards these domains relative to women in a control condition. The potential role of the working self-concept in mediating social category priming effects as well as the practical implications of these findings are discussed.     

College professors’ perceptions of students who stutter and the impact on comfort approaching professors

PurposePrevious literature has documented that college professors view hypothetical students who stutter more negatively than their fluent peers. The purpose of the present study was to investigate whether individuals who stutter report they experience more negative perceptions in the college classroom, and the impact of those perceptions on their comfort approaching professors.MethodsTwo hundred forty-six adults who do and do not stutter, matched for age, participated in this study. Participants were presented with 16 positive and negative personality traits and asked to rate how strongly they believed their professor viewed them along each trait. All participants were asked whether they felt comfortable approaching their professors to discuss their performance. Adults who stutter were asked additional questions to investigate their college experience more comprehensively.ResultsAdults who stutter reported they experienced significantly more negative perceptions from their professors than adults who do not stutter, and were significantly less likely to feel comfortable approaching their professors. These reported negative perceptions, specifically being perceived as less self-assured, predicted comfort approaching professors to receive performance feedback for adults who stutter. Finally, amongst adults who stutter, perception of how they were evaluated compared to their peers was significantly related to comfort approaching professors.ConclusionsResults support that the negative perceptions towards hypothetical students who stutter reported in previous literature are experienced by individuals who stutter, and that these perceptions drive comfort approaching professors for performative feedback. Results suggest professors may increase students’ comfort by clearly outlining equality in evaluation procedures.     

The Peer Attitudes Toward Children who Stutter scale: Reliability, known groups validity, and negativity of elementary school-age children's attitudes

Psychometric properties of the Peer Attitudes Toward Children who Stutter (PATCS) scale (Langevin, M., & Hagler, P. (2004). Development of a scale to measure peer attitudes toward children who stutter. In A.K. Bothe (Ed.), Evidence-based treatment of stuttering: empirical bases and clinical applications (pp. 139–171). Mahwah, NJ: Lawrence Erlbaum Associates.) and the extent to which peer attitudes are negative were re-examined. Results show that internal consistency was .97 and test–retest reliability was .85. In a known groups analysis participants who had contact with someone who stutters had statistically significant higher mean scores (more positive attitudes) than those who had not had contact. Nonsignificant findings for gender and grade call into question the usefulness of these variables as discriminators in future tests of known groups validity of peer attitudes toward children who stutter. Approximately one-fifth of participants had PATCS scores that were somewhat to very negative. These findings support calls for school-based education about stuttering.

Educational objectives

The reader will be able to: (1) summarize the social impacts of stuttering on school-age children who stutter, (2) describe the known groups method to test construct validity, (3) evaluate the psychometric properties of the Peer Attitudes Toward Children who Stutter scale, and (4) provide information about the proportion of students who appear to hold negative attitudes toward children who stutter.     

Scale development to measure attitudes toward unauthorized migration into a foreign country

This study reports on the development and cross-national utility of a Likert type scale measuring attitudes toward unauthorized migration into a foreign country in two samples from "migrant-sending" nations. In the first phase a pool of 86 attitude statements were administered to a sample of 505 undergraduate students in Bulgaria (22.5% male; M age = 23, SD = 4.8). Exploratory factor analysis resulted in six factors, and a reduction to 34 items. The results yielded an overall alpha of (0.92) and alpha for subscales ranging from 0.70 to 0.89. In the second phase the 34-item scale was administered in a survey of 180 undergraduates from Sofia University in Bulgaria (16.7% male, M age = 23, SD = 4.8), plus 150 undergraduates from Hanoi State University in Vietnam (14.7% male, M age = 19, SD = 1.8). Results yielded a 19-item scale with no gender differences, and satisfactory alpha coefficients for a Vietnamese and Bulgarian sample of 0.87 and 0.89 respectively. This scale, equally applicable in both samples, includes items that reflect salient topics of concept of attitudes towards unauthorized migration. An exploratory principal component analysis of the Bulgarian and Vietnamese version of the 19-item scale yielded three factors accounting for 54% and 47% of the variance respectively. A procrustes analysis indicates high conceptual equivalence in the two samples for factor 1 and 2, and moderate for factor 3. This study lends support to the idea that despite different cultural meanings there is a common meaning space in culturally diverse societies.     

A survey of communicative disorders students' attitudes toward stuttering

Cooper's (1975) Clinician Attitudes Toward Stuttering (CATS) inventories were conpleted by 1,902 speech-language pathology and audiology students from 33 universities, each in a different state. The majority of respondents perceived stutterers as having psychosocial problems and believed that client and parental counseling were essential aspects of treatment. These views were relatively unaffected by student training and clinical exposure. In addition, most of the assumptions of Johnson's diagnosogenic theory of stuttering were held by the majority of the students surveyed. Most of the respondents believed that stuttering was difficult to modify and that speech clinicians were neither adept nor comfortable treating stutterers. These latter attitudes were significantly affected by training, i.e., the more advanced the students' training, the more pessimistic their views on clinician competence. Other professional attitudes and the effect of training on them are also discussed.     

The Public Opinion Survey of Human Attributes--Stuttering (POSHA-S): summary framework and empirical comparisons

Purpose

The Public Opinion Survey of Human Attributes-Stuttering (POSHA-S) was developed to make available worldwide a standard measure of public attitudes toward stuttering that is practical, reliable, valid, and translatable. Mean data from past field studies as comparisons for interpretation of POSHA-S results are reported.

Method

Means for POSHA-S items (converted to −100 to +100 scales), components comprising clusters of items, subscores comprising clusters of components, and Overall Stuttering Scores comprising two subscores for stuttering were generated from 64 samples, totaling 2876 respondents who completed experimental versions of the POSHA-S.

Discussion

Lowest, highest, and median sample values, which vary with the addition of new sample data to the growing POSHA-S database archive, provide points of comparison for any potential sample rather than predetermined values.

Conclusions

The final POSHA-S, together with an ongoing and growing archive, can provide increasingly meaningful comparisons for stakeholders measuring public attitudes toward stuttering.Educational objectives: (1) Describe the subscores and components of the POSHA-S, (2) describe the Overall Stuttering Score of the POSHA-S, and (3) describe the format for interpretation of the POSHA-S.     

Language skills of children during the first 12 months after stuttering onset

PurposeTo describe the language development in a sample of young children who stutter during the first 12 months after stuttering onset was reported.MethodsLanguage production was analysed in a sample of 66 children who stuttered (aged 2–4 years). The sample were identified from a pre-existing prospective, community based longitudinal cohort. Data were collected at three time points within the first year after stuttering onset. Stuttering severity was measured, and global indicators of expressive language proficiency (length of utterances and grammatical complexity) were derived from the samples and summarised. Language production abilities of the children who stutter were contrasted with normative data.ResultsThe majority of children’s stuttering was rated as mild in severity, with more than 83% of participants demonstrating very mild or mild stuttering at each of the time points studied. The participants demonstrated developmentally appropriate spoken language skills comparable with available normative data.ConclusionIn the first year following the report of stuttering onset, the language skills of the children who were stuttering progressed in a manner that is consistent with developmental expectations.     

Birth weight and stuttering: Evidence from three birth cohorts

PurposePrevious studies have produced conflicting results with regard to the association between birth weight and developmental stuttering. This study sought to determine whether birth weight was associated with childhood and/or adolescent stuttering in three British birth cohort samples.MethodsLogistic regression analyses were carried out on data from the Millenium Cohort Study (MCS), British Cohort Study (BCS70) and National Child Development Study (NCDS), whose initial cohorts comprised over 56,000 individuals. The outcome variables were parent-reported stuttering in childhood or in adolescence; the predictors, based on prior research, were birth weight, sex, multiple birth status, vocabulary score and mother's level of education. Birth weight was analysed both as a categorical variable (low birth weight, <2500 g; normal range; high birth weight, ≥4000 g) and as a continuous variable. Separate analyses were carried out to determine the impact of birth weight and the other predictors on stuttering during childhood (age 3, 5 and 7 and MCS, BCS70 and NCDS, respectively) or at age 16, when developmental stuttering is likely to be persistent.ResultsNone of the multivariate analyses revealed an association between birth weight and parent-reported stuttering. Sex was a significant predictor of stuttering in all the analyses, with males 1.6–3.6 times more likely than females to stutter.ConclusionOur results suggest that birth weight is not a clinically useful predictor of childhood or persistent stuttering.
