The effects of questionnaire length and lottery ticket inducement on the response rate in mail surveys

Abstract

As part of a study on functional gastrointestinal disorders in the Australian community, we surveyed 500 subjects to test the effects of questionnaire length and lottery inducement on the response rate in mail surveys. By random allocation, n = 124 subjects received a short form questionnaire (28 pages) with a lottery ticket, n = 126 received a short form with no lottery ticket, n= 124 received a long form (32 pages) with a lottery ticket and n= 126 received a long form with no lottery ticket. The overall response rate for the study was 74%. The response rates for the short (76.8%) versus long (71.2%) form and lottery ticket (74.2%) versus no lottery ticket (73.8%) were not significantly different. Significantly more short forms compared with longer forms were received after each stage of the follow-up protocol. A long questionnaire can however be successfully used in survey research.     

Effectiveness of a Hearing Conservation and Vocal Hygiene Program for Kindergarten Children

Abstract

Noise-induced hearing loss and disorders of the voice are two potentially preventable communication disorders. This study sought to determine if young children's knowledge regarding potentially abusive hearing and voice behaviors can be changed through education. An interactive educational program-“Ears for Listening, Voice for Speaking” (ELVS)-was presented to 66 kindergarten students. A questionnaire, testing the students' knowledge regarding anatomy, abusive behaviors, and conservation practices, was administered pre- and post-ELVS participation. A statistically significant increase was found in the students' knowledge post-ELVS participation. Scores on the voice questions were lower than hearing, and, although the difference was not statistically significant, girls scored higher than boys, both pre- and post-ELVS participation. This study highlights the importance of early intervention through education in preventing noise-induced hearing loss and voice disorders.     

EDITORS' INTRODUCTION

ABSTRACT

Transsexualism implies that an anatomically normal individual feels that he or she is actually a member of the opposite sex. Treatment usually includes real-life experience along with hormone therapy and sex reassignment surgery. Voice modification surgery may be necessary, as pass ability in general is still in a large extent dependent on the aspects of voice in transsexual people. Often male-to-female patients report being addressed in telephone conversations as their genetic gender, which is experienced as a disability. The purpose of this study was to evaluate the impact of voice on the quality of life in transsexuals.

In order to detect the disability caused by a voice disorder, the validated assessment method the Voice Handicap Inventory (VHI) was used. An additional question about the way patients were addressed in a telephone conversation was added.

As part of a study describing general health in transsexual persons, done at the Ghent University Hospital Belgium, a total of 48 patients were evaluated. In female-to-male transsexuals the median scores were very low, suggesting testosterone treatment led to an acceptable voice alteration. A higher serum LH level was significantly correlated with higher total, functional and emotional VHI scores. In male-to-female transsexuals the scores were significantly higher than those of the female-to-male transsexuals, but still there was no indication of a real disability/handicap. The extra telephone question was scored higher suggesting male-to-female transsexuals did experience a disability caused by their voice. From this study it is concluded that the VHI values did not demonstrate a handicapping effect.     

Meta-analysis of CBT for Bulimia Nervosa: Investigating the Effects Using DSM-III-R and DSM-IV Criteria

This meta-analysis reports the effects of cognitive-behavioural treatment (CBT) on bulimia nervosa as defined by the DSM-III-R or DSM-IV criteria. In a previous meta-analysis, 26 studies were included using less strict diagnostic criteria for inclusion. The present meta-analysis only included randomized controlled studies fulfilling the DSM-III-R or DSM-IV criteria. Computer searches in MedLine, PsychLIT and references cited herein resulted in a large number articles, of which only seven fulfilled the criteria for inclusion. Effect sizes for binge eating and purging frequency were estimated using both between-group (treatment vs control) and within-group (pre- vs post-treatment) comparisons. The combined within-group effect size for binge eating was r = 0.55 ( d = 1.32) and for purging r = 0.61 ( d = 1.54). The corresponding combined effects for the between-group comparisons were r = 0.23 ( d = 0.47) and r = 0.28 ( d = 0.58), respectively. The combined probabilities for frequency of purging in between- and within-group comparisons were p = 0.00001 and p = 0.00000001, respectively. Although the number of studies included in the meta-analysis was limited, the obtained results are in line with the findings of the previous meta-analysis, and support the efficacy of CBT for the treatment of bulimia nervosa. This suggestion is also supported by the fact that in all the studies except one, comparison groups had received other active treatments.     

The Warpy Thoughts Scale: a New 20‐Item Instrument to Measure Dysfunctional Attitudes

Cognitive theories of psychopathology propose that specific negative cognitive schema held by individuals can increase their likelihood of experiencing depressive episodes. While it has been argued that such dysfunctional attitudes are state measures that occur primarily during periods of depression, a range of research has supported the view that holding dysfunctional attitudes is ongoing, persisting prior to and following depressive episodes. To date, the need for a parsimonious measure of dysfunctional attitudes has not been well addressed. Using data provided by 4545 participants in a free on‐line cognitive behavioural therapy program, MoodGYM, we have developed the Warpy Thoughts Scale (WTS), a 20‐item instrument measuring dysfunctional attitudes. This scale provides 3 first order factors (Relationships, Achievements and Entitlements) and a higher order factor, Warpy Thoughts, from which a Warpy Thoughts score can be obtained. Confirmatory factor analyses on this model indicated that it provides robust results for men and women and for individuals in a wide range of ages. WTS scores were moderately correlated with levels of depressive and anxiety symptoms (0.39 and 0.40, respectively) and explained up to one‐fifth of the variance of these mental health measures. Further validation of the WTS against other measures of dysfunctional thoughts is required.     

表象测量方法述评

表象测量在训练领域广泛应用,也是训练成败的关键环节.表象测量方法可分为口头报告纸笔法、实验操作法,以及神经科学技术共三种方法.其中纸笔报告法以量表测量为主,包括Betts量表、视觉表象清晰度量表及其修订版和运动表象清晰度量表及其修订版;实验操作法以心理旋转为基本范式;神经科学技术主要以经颅磁刺激和功能磁共振成像为主,测量多种表象过程中不同脑区兴奋性.三者各有优劣,均有待提高和改进.     

Interoception and gender: What aspects should we pay attention to?

Interoception is involved in both somatic and mental disorders with different prevalence between genders; however, gender differences are often neglected. To examine the potential gender differences in interoceptive awareness, we recruited 376 healthy subjects (51% males, aged 17–30 years), to fill in the Multidimensional Assessment of Interoceptive Awareness (MAIA). Of that sample, in a subgroup of 40 subjects (50% males), interoceptive accuracy was assessed by heartbeat counting task (HCT).The results on interroceptive awareness suggest that females tend to notice bodily sensations more often, better understand relations between bodily sensations and emotional states, worry or experience more emotional distress with sensations of pain or discomfort and see body as less safe. The results of interoceptive accuracy further suggest that females are less efficient in consciously detecting heartbeats. Therefore, gender should be considered when interoceptive evaluation is performed in disorders associated to bodily sensations and to the emotional/mood states.     

Sluggish cognitive tempo in children and adolescents with higher functioning autism spectrum disorders: Social impairments and internalizing symptoms

Sluggish cognitive tempo (SCT) was introduced in 1980s in the field of attention deficit hyperactivity disorder (ADHD). Studies indicate that symptoms of SCT are separate from symptoms of ADHD and independently associated with multiple domains of functioning in clinical groups and in typical development. We assessed whether similar pattern would apply to higher functioning autism spectrum disorders (ASD). Children with higher functioning ASD (N = 55; 5?15 years) were divided into the ASD+High SCT (n = 17), the ASD+Medium SCT (n = 18) and the ASD+Low SCT (n = 20) groups based on parent‐rated daydreaming and slowness on the Five to Fifteen questionnaire (FTF). The groups were compared on SCT‐related impairments found in previous studies: social skills, academic functioning, psychiatric symptoms, and processing speed. Assessment methods were the FTF, the Development and Well‐Being Assessment, and the Coding subtest of the WISC‐III. The ADHD symptoms were statistically controlled due to the overlap between SCT and ADHD. The ASD+High SCT and ASD+Medium SCT groups were significantly more likely to have the most pronounced social impairments, and the ASD+High SCT group had significantly higher rate of internalizing disorders compared to the ASD+Low SCT group. Our results suggest that children with higher functioning ASD and high or medium levels of SCT symptoms could be at higher risk for psychosocial impairments than children with higher functioning ASD with low levels of SCT symptoms. Co‐occurring ADHD symptoms do not explain the finding. Recognizing SCT symptoms in higher functioning ASD would be important to targeting preventive support.

Gender differences on the Five to Fifteen questionnaire in a non‐referred sample with inattention and hyperactivity‐impulsivity and a clinic‐referred sample with hyperkinetic disorder

Lambek, R., Trillingsgaard, A., Kadesjö, B., Damm, D. & Thomsen, P. H. (2010). Gender differences on the Five to Fifteen questionnaire in a non‐referred sample with inattention and hyperactivity‐impulsivity and a clinic‐referred sample with hyperkinetic disorder. Scandinavian Journal of Psychology 51, 540–447. The aim of the present study was to examine gender differences in children with inattention, hyperactivity, and impulsivity on the Five to Fifteen (FTF) parent questionnaire. First, non‐referred girls (n = 43) and boys (n = 51) with problems of attention and hyperactivity‐impulsivity and then clinic‐referred girls (n = 35) and boys (n = 66) with hyperkinetic disorder (HKD) were compared on the FTF. Results suggested that non‐referred boys were more hyperactive‐impulsive than non‐referred girls, whereas clinic‐referred boys and girl with HKD were more similar than dissimilar on the FTF questionnaire. Secondly, it was examined whether the application of gender mixed norms versus gender specific norms would result in varying proportions of clinic‐referred children with HKD being identified as impaired on the subdomains of the FTF questionnaire. Based on results it was concluded that the use of a gender mixed normative sample may lead to overestimation of impairment in boys with HKD, but the type of sample applied to define impairment on the FTF should depend on the purpose for applying the questionnaire.
