Cross-Cultural Adaptation, Reliability, and Validity of the Turkish Sensory Responsiveness Questionnaire

IMPORTANCE

Sensory processing difficulties are commonly seen in people with mental disorders. However, no questionnaires specific to Turkish culture are available for people with mental disorders.

OBJECTIVE

To examine the cultural adaptation, reliability, and validity of the Turkish Sensory Responsiveness Questionnaire (SRQ).

DESIGN

Causal comparative groups design.

SETTING

Homes, clinics, hospitals, and therapy practices in Turkey.

PARTICIPANTS

A total of 913 participants, of whom 529 were participants ages 18-60 yr with mental disorders.

OUTCOMES AND MEASURES

The cross-cultural adaptation and translation procedures were conducted following Beaton's guidelines. Internal consistency was examined with Cronbach's α. Criterion-related validity of the SRQ was determined with the Adolescent/Adult Sensory Profile using construct validity and was examined by confirmatory factor analysis (CFA) using IBM SPSS Statistics (Version 23) and AMOS (Version 24.0).

RESULTS

In CFA, model fit indices showed an acceptable fit. Test-retest reliability was excellent for the hedonic and avoidance subfactor scores and for the total score (intraclass correlation coefficients = .973, .988, and .974, respectively). Internal consistency was high for the hedonic subfactor (.812) and the avoidance subfactor (.815). Participants with bipolar disorder had the highest scores on the hedonic subfactor, whereas those with schizophrenia had the highest scores on the avoidance subfactor.

CONCLUSIONS AND RELEVANCE

The 36-item SRQ is reliable and valid for analyzing the sensory processing abilities of adults in the Turkish population. Plain-Language Summary: People with mental disorders commonly have difficulties with sensory processing. No sensory responsiveness questionnaire specific to the Turkish population or culture is available for people with mental disorders. This study shows that the current form of the Turkish Sensory Responsiveness Questionnaire can contribute to understanding the sensory processing abilities of Turkish people with and without mental disorders.

Hypersensitivity to Distractors in Fragile X Syndrome from Loss of Modulation of Cortical VIP Interneurons

Attention deficit is one of the most prominent and disabling symptoms in Fragile X syndrome (FXS). Hypersensitivity to sensory stimuli contributes to attention difficulties by overwhelming and/or distracting affected individuals, which disrupts activities of daily living at home and learning at school. We find that auditory or visual distractors selectively impair visual discrimination performance in humans and mice with FXS but not in typically developing controls. In both species, males and females were examined. Vasoactive intestinal polypeptide (VIP) neurons were significantly modulated by incorrect responses in the poststimulus period during early distractor trials in WT mice, consistent with their known role as error signals. Strikingly, however, VIP cells from Fmr1 -/- mice showed little modulation in error trials, and this correlated with their poor performance on the distractor task. Thus, VIP interneurons and their reduced modulatory influence on pyramidal cells could be a potential therapeutic target for attentional difficulties in FXS.SIGNIFICANCE STATEMENT Sensory hypersensitivity, impulsivity, and persistent inattention are among the most consistent clinical features of FXS, all of which impede daily functioning and create barriers to learning. However, the neural mechanisms underlying sensory over-reactivity remain elusive. To overcome a significant challenge in translational FXS research we demonstrate a compelling alignment of sensory over-reactivity in both humans with FXS and Fmr1 -/- mice (the principal animal model of FXS) using a novel analogous distractor task. Two-photon microscopy in mice revealed that lack of modulation by VIP cells contributes to susceptibility to distractors. Implementing research efforts we describe here can help identify dysfunctional neural mechanisms associated not only with sensory issues but broader impairments, including those in learning and cognition.

Electrophysiological evidence for increased auditory crossmodal activity in adult ADHD

Background

Attention deficit and hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by core symptoms of inattention, and/or impulsivity and hyperactivity. In order to understand the basis for this multifaceted disorder, the investigation of sensory processing aberrancies recently reaches more interest. For example, during the processing of auditory stimuli comparable low sensory thresholds account for symptoms like higher distractibility and auditory hypersensitivity in patients with ADHD. It has further been shown that deficiencies not only exist on an intramodal, but also on a multimodal level. There is evidence that the visual cortex shows more activation during a focused auditory task in adults with ADHD than in healthy controls. This crossmodal activation is interpreted as the reallocation of more attentional resources to the visual domain as well as deficient sensory inhibition. In this study, we used, for the first time, electroencephalography to identify a potential abnormal regulated crossmodal activation in adult ADHD.

Methods

15 adult subjects with clinically diagnosed ADHD and 14 healthy controls comparable in age and gender were included. ERP components P50, P100, N100, P200 and N200 were measured during the performance of a unimodal auditory and visual discrimination task in a block design. Sensory profiles and ADHD symptoms were assessed with inattention as well as childhood ADHD scores. For evaluating intramodal and crossmodal activations, we chose four EEG channels for statistical analysis and group-wise comparison.

Results

At the occipital channel O2 that reflects possible crossmodal activations, a significantly enhanced P200 amplitude was measured in the patient group. At the intramodal channels, a significantly enhanced N200 amplitude was observed in the control group. Statistical analysis of behavioral data showed poorer performance of subjects with ADHD as well as higher discrimination thresholds. Further, the correlation of the assessed sensory profiles with the EEG parameters revealed a negative correlation between the P200 component and sensation seeking behavior.

Conclusion

Our findings show increased auditory crossmodal activity that might reflect an altered stimulus processing resource allocation in ADHD. This might induce consequences for later, higher order attentional deployment. Further, the enhanced P200 amplitude might reflect more sensory registration and therefore deficient inhibition mechanisms in adults with ADHD.

Hypersensitivity to distractors in Fragile X syndrome from loss of modulation of cortical VIP interneurons

Attention deficit is one of the most prominent and disabling symptoms in Fragile X Syndrome (FXS). Hypersensitivity to sensory stimuli contributes to attention difficulties by overwhelming and/or distracting affected individuals, which disrupts activities of daily living at home and learning at school. We find that auditory or visual distractors selectively impair visual discrimination performance in both humans and mice with FXS, but not their typically developing controls. Vasoactive intestinal polypeptide (VIP) neurons were significantly modulated by incorrect responses in the post-stimulus period during early distractor trials in WT mice, consistent with their known role as 'error' signals. Strikingly, however, VIP cells from Fmr1-/- mice showed little modulation in error trials, and this correlated with their poor performance on the distractor task. Thus, VIP interneurons and their reduced modulatory influence on pyramidal cells, could be a potential therapeutic target for attentional difficulties in FXS.

Work participation, sensory processing and sleep quality in adults with attention deficit hyperactive disorder

BACKGROUND: Although studies have indicated significant effects of attention-deficit hyperactive disorder (ADHD) on work participation, the mechanism underlying work participation of adults with ADHD is still unclear. OBJECTIVE: Following the World Health Organization’s international classification of functioning, disability, and health concepts, this study compares sensory processing and sleep quality (body functions) with work participation among adults with and without ADHD and examines predictive relationships among adults with ADHD. METHODS: Sixty-nine adults with ADHD and 52 matched controls completed a sociodemographic questionnaire, the Adult/Adolescent Sensory Profile, the Mini Sleep Questionnaire, and the Occupational Questionnaire. RESULTS: The ADHD group had significantly poorer body functions, sensory processing (i.e., low-registration, sensory-sensitivity, and sensation-avoiding patterns), sleep quality, and work performance compared to the control group (p <  .001). For adults with ADHD, sensory sensitivity accounted for 10.9%, and sleep quality accounted for 22.0%, of the variance in their work performance. CONCLUSIONS: The deficient body functions of adults with ADHD may affect their work performance and therefore should be considered in further research, as well as in clinical applications.

The impact of atypical sensory processing on adaptive functioning within and beyond autism: The role of familial factors

LAY ABSTRACT

Individuals diagnosed with autism tend to process sensory information differently than individuals without autism, resulting for instance in increased sensitivity to sounds or smells. This leads to challenges in everyday life and may restrict the individual's daily functioning. How direct this link is, however, is currently unclear. We investigated this question in 289 twins of whom 60 were diagnosed with autism and further 61 were diagnosed with other neurodevelopmental disorders. We looked at the association between unusual sensory processing and adaptive skills, both across individuals and within-twin pairs, testing whether individuals with higher levels of atypical sensory processing showed reduced adaptive skills compared to their twins. Since twins share 50%-100% of their genes and part of their environment (e.g. family background), associations within-twin pairs are free from effects of these familial factors. We found that an increased sensitivity to, as well as the avoiding of, sensory input (hyper-responsiveness) was linked to reduced adaptive skills across individuals-but not within-twin pairs. We also found an association between the degree to which individuals seek for sensory input (sensation seeking) and reduced adaptive skills, but only in individuals diagnosed with autism. The results suggest that sensory hyper-responsiveness has negative effects on individuals' general ability to function, but that this link is influenced by familial factors and hence not direct. In addition, sensation seeking behaviors might have a negative impact on adaptive skills specifically in autistic individuals.

Occupational therapy for adults with intellectual disabilities and sensory processing challenges: a Delphi study exploring practice within acute assessment and treatment units

Purpose

Lack of research means guidance regarding the most effective sensory interventions for adults with intellectual disabilities is limited. Preliminary consensus evidence was created by gathering experienced occupational therapists’ views on practice. The purpose of this study was to establish important elements of practice when using sensory integration-informed approaches on assessment and treatment units.

Design/methodology/approach

A modified Delphi process was used to gather, explore and synthesise the views of 13 occupational therapists. Data was collected via online surveys and included quantitative importance ratings and qualitative comments.

Findings

An experienced panel was in strong agreement regarding many elements of practice they felt were important for use in this setting, and a list of important practice items was created. Two themes were identified: “Complexity” and “Pragmatism vs. Ideal World.” The themes highlight challenges to practice in this area and the complex clinical reasoning used to overcome these.

Research limitations/implications

Participants disagreed about the level of importance of a substantial number of items, therefore items that did not reach consensus may still be important.

Practical implications

This study indicates potentially helpful clinical tools, facilities and training and identifies support needed for occupational therapists working in these settings.

Originality/value

This study contributes to the body of knowledge regarding how occupational therapists do and could work with people with intellectual disabilities and sensory integration difficulties. Although this study takes a UK and Ireland perspective, similar agendas regarding care and support for those with intellectual disabilities internationally mean findings are relevant more widely.

Sensory processing patterns of young adults with preterm birth history

PURPOSE/AIM

This study aimed to evaluate the sensory processing abilities of young adults with a history of preterm birth and the factors affecting these abilities.

MATERIALS AND METHODS

Thirty-seven young adults with preterm birth history were included. After recording their sociodemographic data, sensory processing functions were evaluated using the Adolescent/Adult Sensory Profile. The participants' data were compared to normative samples.

RESULTS

Mean score was 43.51 ± 8.29 for sensory sensitivity, 44.45 ± 9.19 for sensation avoiding, 33.43 ± 8.45 for low registration, and 47.97 ± 9.91 for sensation seeking. Compared to normative samples, 78% of participants in sensation avoiding quadrant, 62% of participants in sensory sensitivity quadrant, 40% of participants in low registration quadrant and sensation seeking quadrant had atypical scores. When sensory profile scores were analysed according to mode of birth, percentages of typical sensory sensitivity and sensation avoiding were low in both the normal vaginal and caesarean delivery subgroups. When analysed by gestational age at birth, ratios of abnormality in sensation avoiding were similar between individuals with very early, early, and late preterm delivery history. Statistically significant difference was found in low registration and sensation avoiding quadrants according to mode of birth (p < .05). There were no statistically significant sex-based and gestational age at birth differences in any of the four quadrants of the sensory profile in the preterm group (p > .05).

CONCLUSION

These results showed that young adults with preterm birth history have differences in sensory processing compared to the general population and should be evaluated for sensory processing patterns.

Links between self-injury and suicidality in autism

BACKGROUND

Autistic individuals without intellectual disability are at heightened risk of self-injury, and appear to engage in it for similar reasons as non-autistic people. A wide divergence of autistic perspectives on self-injury, including those who frame it as a helpful coping mechanism, motivate investigating the link between self-injury, suicide ideation, and attempts which has been reported in typically developing individuals.

METHOD

One hundred three autistic participants completed the Non-Suicidal Self-Injury Assessment Tool (NSSI-AT), the Suicide Behaviors Questionnaire (SBQ-R), and the Interpersonal Social Evaluation List (ISEL-12) across two online studies. Logistic regression was conducted to predict self-harming status via responses to questions on suicidality, and to predict whether certain self-injurious behaviors, including cutting, were especially associated with suicide ideation and attempts. Non-parametric correlation analysis examined relationships between suicide ideation/attempts and other variables that might characterize self-harmers especially at risk of suicidality. These included perceived access to social support, purposes or reasons for self-injury, the number of different self-injurious behaviors engaged in, the duration and lifetime incidence of self-injury, and the individual's feelings about their self-injury.

RESULTS

While self-injuring status was significantly predicted by responses to a question on suicide ideation and attempts, there was no relationship between suicide ideation/attempts and a participant's personal feelings about their self-injury. The method of cutting was also predicted by suicide ideation and attempts, though other methods common in autistic people were at borderline significance. Use of self-injury for the regulation of low-energy emotional states like depression, for self-punishment or deterrence from suicide, and for sensory stimulation, was associated with suicide ideation and attempts, as was the number of self-injurious behaviors engaged in. There was no significant relationship between suicide ideation/attempts and the duration and lifetime incidence of self-injury or social support.

CONCLUSIONS

These preliminary data suggest that while individuals might frame their self-injury as a positive or neutral thing, there remains a concerning relationship between self-injury and suicidality which exists regardless of individual feelings on self-injury. This is consistent with the theoretical perspective that self-injury can be a "gateway" through which individuals acquire capability for lethal suicidal behaviors. The data highlight that particular methods (cutting) and reasons for self-injury may be of significant concern, but this information, which might be of extreme value for clinicians, requires further investigation and validation.

An exploration of sensory processing patterns and their association with demographic factors in healthy adults

Purpose

Previous research has provided limited evidence on whether and how demographic factors associate with sensory processing patterns (SPP) in adults. This paper aims to examine relationships between SPPs and sociodemographic factors of age, sex, education and ethnicity in healthy adults.

Design/methodology/approach

A cross-sectional study design was used. A total of 71 adult participants was recruited from the community, using convenience sampling. Each participant completed the Adolescent/Adult Sensory Profile (AASP) and the Depression Anxiety Stress Scales – short version (DASS-21). Demographic information on age, sex, education and ethnicity was collected. Results were analysed using descriptive statistics and multivariate analyses of covariance (MANCOVA).

Findings

SPPs, as measured by the AASP, were significantly correlated to demographic factors of age and education after controlling for emotional distress using the DASS-21. A statistically significant multivariate effect was found across the four dependent variables (low registration, seeking, sensitivity and avoiding) for the age category, F = 6.922, p = 0.009, ηp2 = 0.145, in the presence of a covariate DASS. The education category showed significance only in the seeking domain (p = 0.008, ηp2 = 0.10) after controlling for DASS. There was no significant correlation between SPPs and gender or ethnicity. Results also indicated that mean scores of participants in this study were “similar to most people” as standardised in the AASP.

Research limitations/implications

This was a cross-sectional study with limitations including that the study used a relatively small sample and was based on self-reported healthy participants.

Practical implications

SPPs may correlate with healthy adults’ age and to a lesser extent education. This suggests that it might be helpful to consider such demographic factors when interpreting SPPs in clinical populations, although further research in larger samples is needed to reach firmer conclusions about possible implications of demographic variables.

Originality/value

The findings in this paper add to the growing evidence that suggest that SPPs vary with sociodemographic factors.

Sensory characteristics of youth at clinical high risk for psychosis

AIM

To identify and compare the sensory characteristics of young people at clinical high risk (CHR) for psychosis to those of peers at clinical low risk (CLR), and to national normative data. CHR and CLR participants were recruited from 6 US regions.

METHOD

A descriptive cohort design was used to analyse baseline data collected as part of the Early Detection and Intervention for the Prevention of Psychosis Program (EDIPPP). Raw scores on the Adolescent/Adult Sensory Profile (AASP) were analysed for 205 young people with CHR and 87 with CLR in 2 age groups: 12 to 17 years (N = 203) and 18 to 25 years (N = 89). ANOVA procedures were used to determine whether differences in AASP scores existed across CLR, CHR, and normative groups by age group.

RESULTS

CHR participants differed significantly from the normative group for all 4 AASP quadrant scores (Low Registration, Sensory Seeking, Sensory Sensitivity and Sensory Avoiding) in both age groups. CLR participants were similar to norms, except for Sensory Seeking scores that were significantly lower than norms in both age ranges.

CONCLUSION

Young people with CHR demonstrate active avoidance, heightened sensitivity, reduced seeking, and reduced registration of sensations in everyday life compared to typical peers. This pattern of differences may be a valuable marker for identifying individuals who are at high risk for developing a psychotic illness, and may also inform interventions designed to prevent or minimize the illness process and accompanying dysfunction.

The association between sensory processing styles and mindfulness

Introduction

Mindfulness is associated with psychological wellbeing and quality of life. The focus on body awareness in definitions of mindfulness suggests that an individual’s sensory processing pattern may influence mindfulness abilities. Therefore, this study seeks to examine the relationship between sensory processing styles and multiple aspects of mindfulness including components of attention, awareness, and acceptance in healthy adults.

Method

151 participants, aged 18 to 60 (mean 25.24 ± 8.8), completed the Adolescent/Adult Sensory Profile, mindful attention and awareness scale, and cognitive and affective mindfulness scale.

Findings

Aspects of mindfulness associated with attention and awareness were significantly negatively related to sensory processing patterns associated with passive behavioral strategies (low registration and sensory sensitivity).

Conclusion

Individuals whose sensory processing patterns are characterized by poor awareness experience more mind wandering and distraction in daily life. Occupational therapists should consider mindfulness techniques when treating individuals with sensory processing disorders. In addition, information about sensory processing styles should be incorporated into relaxation and mindfulness-based interventions.
