Methods for questionnaire design: a taxonomy linking procedures to test goals.

Background: In the clinical field, the use of questionnaires is ubiquitous, and many different methods for constructing them are available. The reason for using a specific method is usually lacking, and a generally accepted classification of methods is not yet available. To guide test developers and users, this article presents a taxonomy for methods of questionnaire design which links the methods to the goal of a test.

Use of the Brief Shame and Guilt Questionnaire in Deaf and Hard of Hearing Children and Adolescents.

No assessment tools are available to measure shame and guilt in children who are deaf or hard of hearing (DHH), while these self-conscious emotions might play a role in the frequently noted social and behavioral problems in this group. Therefore, the aim of this study was to validate the Brief Shame and Guilt Questionnaire (BSGQ) in DHH children. In addition, we examined associations of shame and guilt with social anxiety, self-esteem, delinquency, and psychopathic behaviors.

Reactive/proactive aggression and affective/cognitive empathy in children with ASD.

The main aim of this study was to examine the extent to which affective and cognitive empathy were associated with reactive and proactive aggression, and whether these associations differed between children with an Autism Spectrum Disorder (ASD) and typically developing (TD) children. The study included 133 children (67 ASD, 66 TD, Mage=139 months), who filled out self-report questionnaires. The main findings showed that the association between reactive aggression and affective empathy was negative in TD children, but positive in children with ASD.

The predictive validity of criminogenic needs for male and female offenders: comparing the relative impact of needs in predicting recidivism.

Most instruments used to assess offenders' risk of recidivism were developed and validated on male samples. Use of these instruments with female offenders is, however, common practice. This use with female offenders implies the assumption that the risk of recidivism can be predicted on the basis of the same risk factors for women as for men.

Pathways underlying somatic complaints in children and adolescents who are deaf or hard of hearing.

Frequent somatic complaints are not only a problem in themselves but also related to other difficulties. So far, no conclusive findings have been reported about the prevalence of and factors underlying these complaints in children and adolescents who are deaf or hard of hearing (DHH). Such information would be valuable for prevention and intervention.

Emotion regulation and internalizing symptoms in children with autism spectrum disorders.

The aim of this study was to examine the unique contribution of two aspects of emotion regulation (awareness and coping) to the development of internalizing problems in 11-year-old high-functioning children with an autism spectrum disorder (HFASD) and a control group, and the moderating effect of group membership on this. The results revealed overlap between the two groups, but also significant differences, suggesting a more fragmented emotion regulation pattern in children with HFASD, especially related to worry and rumination. Moreover, in children with HFASD, symptoms of depression were unrelated to positive mental coping strategies and the conviction that the emotion experience helps in dealing with the problem, suggesting that a positive approach to the problem and its subsequent emotion experience are less effective in the HFASD group.

Smile line assessment comparing quantitative measurement and visual estimation.

Introduction: Esthetic analysis of dynamic functions such as spontaneous smiling is feasible by using digital videography and computer measurement for lip line height and tooth display. Because quantitative measurements are time-consuming, digital videography and semiquantitative (visual) estimation according to a standard categorization are more practical for regular diagnostics. Our objective in this study was to compare 2 semiquantitative methods with quantitative measurements for reliability and agreement.

Age-related changes of the dental aesthetic zone at rest and during spontaneous smiling and speech.

The aims of this study were to analyse lip line heights and age effects in an adult male population during spontaneous smiling, speech, and tooth display in the natural rest position and to determine whether lip line height follows a consistent pattern during these different functions. The sample consisted of 122 randomly selected male participants from three age cohorts (20-25 years, 35-40 years, and 50-55 years). Lip line heights were measured with a digital videographic method for smile analysis, which had previously been tested and found reliable.

Tooth display and lip position during spontaneous and posed smiling in adults.

Objective: To analyze differences in tooth display, lip-line height, and smile width between the posed smiling record, traditionally produced for orthodontic diagnosis, and the spontaneous (Duchenne) smile of joy.

Material And Methods: The faces of 122 male participants were each filmed during spontaneous and posed smiling. Spontaneous smiles were elicited through the participants watching a comical movie.

Validity of the visual analogue scale as an instrument to measure self-efficacy in resuscitation skills.

Context: Self-efficacy is an important factor in many areas of medical education, including self-assessment and self-directed learning, but has been little studied in resuscitation training, possibly because of the lack of a simple measurement instrument.

Objective: We aimed to assess the validity of a visual analogue scale (VAS) linked to a single question as an instrument to measure self-efficacy with respect to resuscitation skills by comparing the VAS with a questionnaire and using known-groups comparisons.

Methods: We developed questionnaires to measure self-efficacy for a number of resuscitation tasks and for computer skills.

Smile attractiveness. Self-perception and influence on personality.

Objectives: To investigate self-perception of smile attractiveness and to determine the role of smile line and other aspects correlated with smile attractiveness and their influence on personality traits.

Subjects And Methods: Participants judged their smile attractiveness with a patient-specific questionnaire. The questionnaire contained a spontaneous smiling photograph of the participant.

The children's DEBQ for assessment of restrained, emotional, and external eating in 7- to 12-year-old children.

Objective: Construct an age adapted version of the Dutch Eating Behaviour Questionnaire (DEBQ) for measurement of restrained, emotional and external eating in 7- to 12-year-old children: the DEBQ-C.

Method: The DEBQ-C was constructed and tested for its reliability, factorial validity, factorial invariance for sex, overweight (BMI-status), and age, and correlations with measures for unhealthy life style in one sample (382 boys and 387 girls). In a second sample (252 boys and 263 girls) correlations were obtained with measures for body dissatisfaction and parental feeding styles.

Digital videographic measurement of tooth display and lip position in smiling and speech: reliability and clinical application.

Introduction: Tooth display and lip position in smiling and speech are important esthetic aspects in orthodontics and dentofacial surgery. The spontaneous smile and speech are considered valuable diagnostic criteria in addition to the posed social smile. A method was developed to measure tooth display in both smile types and speech.

Project quality rating by experts and practitioners: experience with Preffi 2.0 as a quality assessment instrument.

Preffi 2.0 is an evidence-based Dutch quality assessment instrument for health promotion interventions. It is mainly intended for both planning and assessing one's own projects but can also be used to assess other people's projects (external use).

Generalizability of a study sample assessment procedure for entrance selection for medical school.

To optimize the validity of instruments for the selection of students for admission to medical school a close resemblance between selection criteria and activities in medical school and patient care is proposed. A study sample assessment procedure (SSAP), focusing on independent studying, collaboration with peers and providing information to standardized patients, was designed and has been applied as a selection tool at UMC Utrecht Medical School since 2001. The interviews with standardized patients are observed and rated on the quality of information provided and the quality of communication.

The oral pigmentation chart: a clinical adjunct for oral pigmentation in removable prostheses.

Purpose: Non-Caucasian patients exhibit different characteristics of oral pigmentation and may request that the acrylic resin parts of their dentures look natural, simulating the original mucosal color. Tooth loss, bone resorption, and lack of attached gingiva may, however, make it difficult to determine what the original pigmentation was like. The purpose of this investigation was to study the distribution in oral pigmentation around the natural dentition in non-Caucasians, in a preliminary effort to classify these variations into a chart of oral pigmentation, and to analyze its reproducibility.

Measuring Strength of Motivation for Medical School.

Purpose: Students vary in their strength of motivation to start and pursue medical training. This study was conducted to investigate the psychometric properties of a Strength of Motivation for Medical School (SMMS) questionnaire.

Method: The questionnaire was designed using an iterative method.

An eight-year follow-up to a randomized clinical trial of participant satisfaction with three types of mandibular implant-retained overdentures.

Studies have shown that mandibular implant overdentures significantly increase satisfaction and quality of life of edentulous elders. Improved chewing ability appears to have a positive impact on nutritional state. Therefore, it is important to determine the best design of this prosthesis over the long term.

Reproducibility and accuracy of automated probe measurements of gingiva and bone levels on stone casts following guided bone regeneration treatment.

Objectives: For evidence-based evaluation of guided bone regeneration (GBR), accurate registration of changes in gingiva and bone levels is needed. A new method is introduced and evaluated.

Methods: In a clinical trial with 30 patients, alginate impressions of the surgical area including the interproximal gingiva and alveolar bone at the adjacent teeth were made in duplicate prior to and during GBR surgery, fixture installation and abutment connection.

Effect of GBR and fixture installation on gingiva and bone levels at adjacent teeth.

Guided bone regeneration (GBR) is frequently used in oral implantology. It is unclear to what extent GBR affects the periodontium of adjacent teeth. Therefore, the present study quantifies changes in the proximal gingiva and bone levels at these teeth in 30 patients.

Detection of genetically divergent clone mates in apomictic dandelions.

This study aims to identify genetically diverged clone mates in apomictic dandelions. Clone mates are defined as individuals that may have diverged as a result of mutation accumulation and that have undergone only clonal reproduction since their most recent common ancestor. Based on distinctive morphology and an aberrant and rare chloroplast haplotype, northwest European individuals of Taraxacum section Naevosa are well suited for the detection of clonal lineages in which mutation has occurred.

The decisional conflict scale: further validation in two samples of Dutch oncology patients.

The importance of patient involvement in medical decision making is indisputable. Yet, decision making concerning medical treatment options is a difficult task for most patients. In order to study decision-making processes in health care, O'Connor developed the decisional conflict scale (DCS).

Assessment of medical students' communicative behaviour and attitudes: estimating the reliability of the use of the Amsterdam attitudes and communication scale through generalisability coefficients.

It is widely accepted that adequate attitudes and communicative skills are among the essential objectives in medical education. The Amsterdam attitude and communication scale (AACS) was developed to assess communicative skills and professional attitudes of medical students. More specifically, it was designed to evaluate the clinical behaviour of clerks to establish their suitability for the medical profession.

Decision support for patients with early-stage breast cancer: effects of an interactive breast cancer CDROM on treatment decision, satisfaction, and quality of life.

Purpose: To investigate the effects of the Interactive Breast Cancer CDROM as a decision aid for breast cancer patients with a choice between breast conserving therapy (BCT) and mastectomy (MT).

Patients And Methods: Consecutive patients with stage I and II breast cancer were enrolled. A quasi-experimental, longitudinal, and pretest/posttest design was used.

Hairpins involving both inverted and direct repeats are associated with homoplasious indels in non-coding chloroplast DNA of Taraxacum (Lactuceae: Asteraceae).

Sequence variation in 2.2 kb of non-coding regions of the chloroplast genome of eight dandelions (Taraxacum: Lactuceae) from Asia and Europe is interpreted in the light of the phylogenetic signal of base substitutions vs. indels (insertions-deletions).
