Use and underuse of mobility aids in individuals with visual impairment: a cross-sectional study of a Norwegian sample

PURPOSE

To examine the use and underuse of mobility aids in individuals with visual impairment.

METHODS

A telephone survey including a probability sample of 736 adults who were members of the Norwegian Association of the Blind and Sighted (response rate: 61%). The interviews took place between January and May 2017, collecting information about access, use, underuse and training in five types of mobility aids (white cane, guide dog, GPS, door-to-door transport and sighted guide). For each mobility aid, we obtained data for underuse defined as non-use despite expecting benefits of use in terms of increased mobility or safety. Participants also answered questions about loneliness (Three-Item Loneliness Scale) and life satisfaction (Cantril's Ladder of Life Satisfaction).

RESULTS

Of the participants, 69% reported using at least one type of mobility aid. Use of specific aids ranged from 12% for the GPS to 52% for door-to-door transport. Estimates of underuse ranged between 14% for door-to-door transport and 28% for GPS. Underuse was not related to lack of resources, as many non-users expecting benefits had access to mobility aids and had undergone training in its use. For example, 81% of non-users of the white cane had access to a cane. In post hoc analyses, non-users who expected benefits from use had lower life satisfaction compared with users.

CONCLUSIONS

Many individuals with visual impairment do not use mobility aids. Strategies that help visually impaired individuals overcome barriers to the use of mobility aids may improve their sense of safety, mobility and quality of life.Implications of rehabilitationThe best mobility aids are those being used. Rehabilitation professionals involved in the provision of mobility aids should be sensitive to the user's lived experiences, and be alert of the cultural meanings of mobility aids and on disability in general.Rehabilitation professionals, social service workers and others need more knowledge of the psychosocial and cultural aspects related to why people do not use their mobility aids.A successful integration of mobility aids in people's daily life cannot be achieved by sufficient accessibility alone. Structured routines for follow-up of those who receive aids should be implemented, so that the aids are actually used.Due to the high rates of underuse and its possible relation to quality of life, promoting regular use of mobility aids should be prioritized.

Visual impairment and employment in Norway

BACKGROUND

Past studies have suggested lower employment of people with visual impairment. Reasons for this are less known. This study aimed to examine the employment rates among people with visual impairment, and its association with sociodemographic characteristics, vision-related factors, depression, and life satisfaction.

METHODS

This cross-sectional study included a stratified random sample of 574 working-age adults (18-67 years) who were members of the Norwegian Association of the Blind and Partially Sighted. Data were collected by telephone interviews between January and May 2017, and included information on work status, sociodemographic factors, vision-related characteristics, depression (Patient Health Questionnaire-9), and life satisfaction (Cantril's Ladder of Life Satisfaction). Associations with employment (full-time, part-time, or self-employment) were examined using regression analyses.

RESULTS

Of the participants, 51.2% of males and 38.1% of females reported to be employed. Employment was associated with being of middle age, male gender, higher education, residing in high-income municipalities, having a moderate degree of vision loss, lower onset-age of vision loss, and having no additional impairments. Employed participants had lower levels of depression compared to others (adjusted exponentiated beta: 0.80, 95% confidence interval (CI): 0.67, 0.96). They also had a higher odds of scoring higher on life satisfaction (adjusted exponentiated beta (odds ratio): 1.85, 95% CI: 1.32, 2.59).

CONCLUSIONS

Employment was lower in people with visual impairment than in the general population. Inclusion of the blind and partially sighted into the workforce could promote health and thus have socio-economic benefits.

Post-Traumatic Stress Disorder in People with Visual Impairment Compared with the General Population

Background: People with a visual impairment appear to have an increased risk of experiencing potentially traumatizing life events and possibly also subsequently developing post-traumatic stress disorder (PTSD). This study investigated the point prevalence of PTSD in people with a visual impairment compared with the general population of Norway and examined factors associated with PTSD among people with a visual impairment. Methods: A telephone-based survey was administered to a probability sample of 1216 adults with a visual impairment. Of these, 736 (61% response rate) participated. A probability sample from the general population served as a reference (n = 1792, 36% response rate). PTSD was measured with the PTSD Checklist for the DSM-5 (PCL-5), based on the currently most bothersome event reported from the Life Events Checklist for DSM-5 (LEC-5). We used the DSM-5 diagnostic guidelines to categorize participants as fulfilling the PTSD symptom criteria or not. Results: The prevalence of PTSD was higher among people with a visual impairment than in the general population, both for men (9.0% vs. 3.8%) and women (13.9% vs. 8.5%). The prevalence rates of PTSD from the illness or injury that had caused the vision loss (men 3.9%, women 2.2%) accounted for a considerable part of the difference between the populations. For women, PTSD related to sexual assaults also contributed significantly to a higher PTSD prevalence in the visually impaired versus the general population (5.2% vs. 2.2%), while for men there were no other event categories which resulted in significant differences. Among people with a visual impairment, the higher risk of PTSD was associated with lower age, female gender, having acquired the vision loss, and having other impairments in addition to the vision loss. Conclusion: The higher prevalence of PTSD in people with a visual impairment suggests that vulnerability to mental health problems is associated with serious life events. The higher incidence than in the general population is partly due to the illness or injury that had led to the vision loss and partly due to people with vision loss appearing to be more vulnerable through exposure to other types of potentially traumatizing events, such as sexual abuse.

Serious Life Events in People with Visual Impairment Versus the General Population

The present study aimed to examine the lifetime exposure to serious life events in people with visual impairment compared with the general population. Data were derived from a telephone survey including a probability sample of 736 adults with visual impairment (response rate: 61%). The lifetime prevalence of direct experiences with seventeen different categories of serious life events (Life Events Checklist for DSM-5 (LEC-5)) were compared to that obtained from the general Norwegian population (N = 1792, 36% response rate). Altogether, 68% of people with visual impairment had been directly exposed to at least one serious life event, with equal rates among males and females (p = 0.59). The prevalence of serious life events was higher than for the general population (60%, p < 0.001), especially for fire or explosions, serious accidents, sexual assaults, life-threatening illness or injury, and severe human suffering. In conclusion, our results indicate that people with visual impairment are more prone to experiencing serious life events. This highlights the need for preventive strategies that reduce the risk of serious life events in this population.

General self-efficacy in individuals with visual impairment compared with the general population

BACKGROUND

Knowledge about self-efficacy and its significance for the quality of life of people with visual impairment is lacking. The aims of the study were to compare general self-efficacy in individuals with visual impairment with the general population, and to investigate the association between self-efficacy and life satisfaction.

METHODS

A telephone-based cross-sectional survey was conducted between January and May 2017 in a probability sample of adults who were members of the Norwegian Association of the Blind and Partially Sighted. Participants were asked questions about their sociodemographic characteristics, characteristics of vision loss, general self-efficacy (General Self-efficacy Scale), and life satisfaction (Cantril's Ladder of Life Satisfaction). We obtained norm data from a representative survey of the general Norwegian population (N = 1792; mean age 53.2 years; 52.5% females).

RESULTS

People with visual impairment had higher levels of general self-efficacy than people in the general population (Mean: 31.5 versus 29.0, p < .001). Results from linear regression analyses of the visual impairment population showed that higher education and residential in an urban municipality were associated with higher self-efficacy. Having additional impairments and a previous history of physical or sexual assaults were associated with lower self-efficacy. A linear dose-response relationship was found between self-efficacy and life satisfaction, in the visual impairment population as well as in the general population.

CONCLUSIONS

People with visual impairment have higher self-efficacy than people in the general population, possibly due to extensive mastery experience in how to handle life as visually impaired. Self-efficacy seems to be important in achieving the best possible life.

The development of posttraumatic stress disorder in individuals with visual impairment: a systematic search and review

PURPOSE

Posttraumatic stress disorder (PTSD) is a mental health problem with a negative impact on quality of life. Little is known about the relationship between PTSD and visual impairment. According to diagnostic criteria for PTSD, vision loss in itself is generally not considered as a traumatic event. PTSD in people with visual impairment is more likely to be the result of traumatic events, which are not directly related, or are only indirectly related to, visual impairment. The purpose of this systematic review was to describe and discuss the literature on the development of PTSD in people with visual impairment.

METHODS

A literature search in PubMed, Embase, PsycINFO and Web of Science was performed up to 15 November 2019 in collaboration with a medical information specialist. Additional search strategies included hand searches of references of retrieved papers and free-text hand searches in Google Scholar. Thematic content analysis of the extracted data was carried out in order to identify main themes and subthemes.

RESULTS

Findings from 13 articles are presented in a narrative manner along three main themes: (1) posttraumatic stress disorder; (2) traumatic events and (3) impact of traumatic events. People with visual impairments may be at higher risk of being exposed to certain potentially traumatic events. Limited/restricted access to situational information during events may contribute to the stressfulness of the experience. Furthermore, visual impairment may shape the impact of traumatic events.

CONCLUSIONS

The current evidence suggests some unique experiences and challenges for people who are visually impaired. PTSD was prevalent in this population, and prevalence rates ranged from 4% to 50%. Future research may focus on gaining insight into the extent and burden of PTSD, and exploring help-seeking behaviour and treatment needs among those with visual impairment and PTSD.

Visual impairment and depression: Age-specific prevalence, associations with vision loss, and relation to life satisfaction

BACKGROUND

To our knowledge, no study has obtained specific estimates of depression for young and middle-aged adults with visual impairment (VI). As estimates of depression varies across age groups in the general population, it is of interest to examine whether the same applies to adults with low vision or blindness.

AIM

To estimate depression prevalence and its association with VI-related characteristics and life satisfaction in adults with VI.

METHODS

A telephone-based cross-sectional survey was conducted between January and May 2017 in an age-stratified sample of adults who were members of the Norwegian Association of the Blind and Partially Sighted. Participants were asked questions about their sociodemographic characteristics, VI characteristics, and life satisfaction. Depression was measured with the Patient Health Questionnaire. The diagnostic scoring algorithm was used to calculate the point prevalence of depression (i.e., major depression and other depressive disorders) across categories of gender and age (years: 18-35, 36-50, 51-65, ≥ 66). The associations were estimated using regression models.

RESULTS

Overall, 736 adults participated in the study (response rate: 61%). The prevalence estimates of depression varied across different age groups, ranging from 11.1%-22.8% in women and 9.4%-16.5% in men, with the highest rates for the two youngest age groups. Results from the multivariable models including sociodemographic and VI-related variables showed that losing vision late in life [Prevalence ratio (PR), 1.76, 95%CI: 1.11, 2.79] and having other impairments (PR: 1.88, 95%CI: 1.32, 2.67) were associated with higher rates of depression, whereas older age was associated with lower rates (PR: 0.83, 95%CI: 0.74, 0.93). Additionally, participants who were depressed had lower life satisfaction than those who were not depressed (adjusted β: -2.36, 95%CI: -2.75, -1.98).

CONCLUSION

Our findings suggest that depression in adults with VI, and especially among young and middle-aged adults, warrants greater attention by user organisations, clinicians, and healthcare authorities.

Social interactions, experiences with adverse life events and depressive symptoms in individuals with visual impairment: a cross-sectional study

BACKGROUND

Knowledge about the high rates of depression in people with visual impairment (VI) remains unclear. The study aimed to examine whether depressive symptoms in people with VI were associated with social isolation, perceived social support and lifetime exposure to bullying, physical abuse or sexual abuse.

METHODS

An anonymous telephone survey was conducted from January to May 2017 in an age-stratified sample of adults with VI who were members of the Norwegian Association of the Blind and Partially Sighted. Participants were asked questions about social isolation, perceived social support, and past experiences with bullying and abuse. Depressive symptoms were measured by the nine-item Patient Health Questionnaire (PHQ-9). We calculated unadjusted and full-adjusted exponentiated beta-values (Exp(β)) and corresponding 95% confidence intervals (CIs) using generalized linear models.

RESULTS

Overall, 736 (61%) adults participated in the study. The mean depression scores were 5.24 (SD: 5.3, range: 0-27), 4.61 for men and 5.77 for women. Results from the full-adjusted model showed higher levels of depressive symptoms among participants who reported social isolation (Exp(β): 1.89, 95% CI: 1.63-2.20), lower levels of perceived social support (Exp(β): 1.55, 95% CI: 1.31-1.83), and past experiences of abuse (Exp(β): 1.41, 95% CI: 1.17-1.70). The strength of the associations between past exposure to bullying or abuse and depressive symptoms was similar for those with low and high levels of support.

CONCLUSION

Social isolation, perceived support and experiences of adverse events appear to be independently associated with depressive symptoms. Thus, social integration may be appropriate for the promotion of mental health among people with VI.

Loneliness among adults with visual impairment: prevalence, associated factors, and relationship to life satisfaction

Background

Little is known about whether and to what extent loneliness impacts the lives of people with visual impairment (VI). Thus, the aim of this study was to examine the prevalence of and factors associated with loneliness in adults with VI, and to examine its association with life satisfaction.

Methods

This cross-sectional interview study included a probability sample of 736 adults (≥18 years old) with VI who were members of the Norwegian Association of the Blind and Partially Sighted. The interviews took place from January to May 2017, collecting information about sociodemographics, VI characteristics, adverse life events, loneliness (Three Item Loneliness Scale), and life satisfaction (Cantril’s Ladder of Life Satisfaction). The prevalence of loneliness was compared to data obtained from the general Norwegian population (N = 14,884; mean age 46.4 years; 50.7% females).

Results

The prevalence of moderate and severe loneliness in the VI population was 28.7% (95% CI: 25.4, 32.1) and 19.7% (95% CI: 16.9, 22.8), respectively. The rates were consistently higher across age groups compared to the general population. Loneliness was associated with younger age, blindness, having other impairments, unemployment, and a history of bullying or abuse. In addition, higher scores on loneliness were associated with lower levels of life satisfaction (fully adjusted β = − 0.48, 95% CI: − 0.55, − 0.41).

Conclusions

Loneliness is common in adults with VI. Strategies capable of reducing loneliness could improve life satisfaction among people who are blind or visually impaired.

Visual impairment and mortality in patients with type 2 diabetes

OBJECTIVE

To evaluate whether visual acuity impairment was an independent predictor of mortality in patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

This is a 19-year follow-up of a cohort of 1241 patients newly diagnosed with type 2 diabetes and aged 40 years or over. Visual acuity was assessed by practicing ophthalmologists both at diabetes diagnosis and after 6 years. The logarithmic value of the visual acuity (logMAR) was the exposure. Multivariable Cox regression models were adjusted for multiple potential confounders including cardiovascular disease, and censored for potential mediators, that is, fractures/trauma. Primary outcomes were from national registers: all-cause mortality and diabetes-related mortality.

RESULTS

Visual impairment at diabetes diagnosis was robustly associated with subsequent 6-year all-cause mortality. Per 1 unit reduced logMAR acuity the incidence rate of all-cause mortality increased with 51% (adjusted HR: 1.51; 95% CI 1.12 to 2.03) and of fractures/trauma with 59% (HR: 1.59; 95% CI 1.18 to 2.15), but visual acuity was not associated with diabetes-related mortality. After censoring for fractures/trauma, visual acuity was still an independent risk factor for all-cause mortality (HR: 1.68; 95% CI 1.23 to 2.30). In contrast, visual acuity 6 years after diabetes diagnosis was not associated with the subsequent 13 years' incidence of any of the outcomes, as an apparent association with all-cause mortality and diabetes-related mortality was explained by confounding from comorbidity.

CONCLUSIONS

Visual acuity measured by ophthalmologists in patients newly diagnosed with type 2 diabetes was an independent predictor of mortality in the short term.

Sexual assaults in individuals with visual impairment: a cross-sectional study of a Norwegian sample

OBJECTIVE

To examine the prevalence of sexual assaults among individuals with visual impairment (VI) compared with the general population and to investigate the association between sexual assault and outcomes of self-efficacy and life satisfaction.

DESIGN

Cross-sectional interview-based study conducted between February and May 2017.

PARTICIPANTS

A probability sample of adults with VI (≥18 years) who were members of the Norwegian Association of the Blind and Partially Sighted. A total of 736 (61%) members participated, of whom 55% were of female gender. We obtained norm data for sexual assaults from a representative survey of the general Norwegian population.

OUTCOME MEASURES

Sexual assaults (Life Event Checklist for DSM-5), self-efficacy (General Self-Efficacy Scale) and life satisfaction (Cantril's Ladder of Life Satisfaction).

RESULTS

The prevalence of sexual assaults (rape, attempted rape and forced into sexual acts) in the VI population was 17.4% (95% CI 14.0 to 21.4) among women and 2.4% (95% CI 1.2 to 4.7) among men. For women, the VI population had higher rates of sexual assaults across age strata than the general population. For men, no significant differences were found. In the population of people with VI, the risk of sexual assault was greater for those having other impairments in addition to the vision loss. Individuals with VI who experienced sexual assaults had lower levels of self-efficacy (adjusted relative risk (ARR): 0.18, 95% CI 0.05 to 0.61) and life satisfaction (ARR: 0.31, 95% CI 0.19 to 0.50) than others.

CONCLUSIONS

The risk of experiencing sexual assault appears to be higher in individuals with VI than in the general population. Preventive measures as well as psychosocial care for those who have been exposed are needed.

Post-traumatic stress reactions among individuals with visual impairments: a systematic review

Purpose: To conduct a systematic review of post-traumatic stress reactions among individuals with visual impairment (VI). Materials and methods: Qualitative and quantitative studies were identified through searches in MEDLINE, EMBASE, PsycINFO, CINAHL, Web of Science, and Cochrane Libraries. The literature search was limited to humans, of English and Scandinavian languages and publication year between 1980 and 2017. Study quality was assessed for all the included studies and extracted data were synthesized using narrative analysis. Results: Of 4235 records identified through literature search, eleven were included in the analyses. Results from the qualitative studies illustrated multiple physical, behavioral, emotional, and cognitive manifestations of trauma. Four out of five quantitative studies showed that various types of potentially traumatic events were significantly associated with mental health adversities (p < 0.05). The prevalence of post-traumatic mental disorders was 4-21.2% for depression, 0.9% for dysthymia, and 32% for substance misuse. The quality of the reviewed studies was considered low to moderate. Conclusion: Traumatic experiences appear to have a great impact on the mental health in people with visual impairment (VI) and these results highlight their need for mental health care. Future studies with higher methodological rigor are recommended. Implications for rehabilitation Visual impairment entails a greater susceptibility to some types of potentially traumatic events, especially threats in everyday life. This calls for a greater emphasis on safe community environments and universal design in public spaces. In rehabilitation after serious accidents or potentially traumatic events, professionals working with people with vision impairment should be aware of the different manifestations of post-traumatic stress responses and that some stress responses may cause additional disability. The high prevalence of traumatic events and their impact on mental health in individuals with visual impairments highlights a need of mental health care.

Bullying among people with visual impairment: Prevalence, associated factors and relationship to self-efficacy and life satisfaction

AIM

To examine associated factors of bullying and to determine associations between bullying and psychosocial outcomes among individuals with visual impairments (VI).

METHODS

We conducted an age-stratified cross-sectional survey of adults with VI who were recruited from the Norwegian Association of the Blind and Partially Sighted. Data were collected through structural telephone interviews in the period between February and May, 2017. Linear regression models were used to examine factors related to bullying and associations of bullying with self-efficacy and life satisfaction.

RESULTS

A total of 736 individuals were interviewed. The lifetime and 6-mo prevalence of bullying was 41.7% and 8.2%, respectively. The majority of bullied participants reported VI-specific bullying (65.1%). Victimization of bullying was associated with young age, early onset-age of VI, and having other impairments. Participants who reported bullying had lower levels of self-efficacy [Adjusted relative risk (ARR): 0.40, 95% confidence interval (CI): 0.19-0.85] and life satisfaction (ARR: 0.68, 95%CI: 0.51-0.91).

CONCLUSION

Bullying is highly prevalent among individuals with VI. Our findings suggest that interventions to reduce bullying may be beneficial for improving the well-being and life quality of people with VI.

How to succeed? Physical activity for individuals who are blind

The aim of our case study was to examine the perceived experiences of participation in physical activity (PA). The cases comprised two individuals with blindness (a girl aged 12 years and a man aged 23 years), both of whom lived in Norway and had succeeded in becoming physically active. Both participants were recruited from Statped, the Norwegian support service for special needs education. Data were gathered from individual structured interviews with open and closed questions. A narrative descriptive analysis was used to analyse the data. The results showed that important factors for the blind participants’ PA participation were having good instructors, support or visual interpreters, active family members, a safe sports environment, having tried many sports, private transportation to the exercise facilities, and a positive social environment, with peers, friends, and family members. Although some differences were found between the participants’ responses, important reasons for them to engage in PA were stated as the sense of fun, energy, and self-esteem that they derived from it, in addition to physical fitness. In conclusion, the study provides knowledge of factors that could increase PA adherence of individuals with blindness being included in PA and sports together with sighted peers.

Self-reported visual impairment, physical activity and all-cause mortality: The HUNT Study

AIMS

To examine the associations of self-reported visual impairment and physical activity (PA) with all-cause mortality.

METHODS

This prospective cohort study included 65,236 Norwegians aged ⩾20 years who had participated in the Nord-Trøndelag Health Study (HUNT2, 1995-1997). Of these participants, 11,074 (17.0%) had self-reported visual impairment (SRVI). The participants' data were linked to Norway's Cause of Death Registry and followed throughout 2012. Hazard ratios and 95% confidence intervals (CI) were assessed using Cox regression analyses with age as the time-scale. The Cox models were fitted for restricted age groups (<60, 60-84, ⩾85 years).

RESULTS

After a mean follow-up of 14.5 years, 13,549 deaths were identified. Compared with adults with self-reported no visual impairment, the multivariable hazard ratios among adults with SRVI were 2.47 (95% CI 1.94-3.13) in those aged <60 years, 1.22 (95% CI 1.13-1.33) in those aged 60-84 years and 1.05 (95% CI 0.96-1.15) in those aged ⩾85 years. The strength of the associations remained similar or stronger after additionally controlling for PA. When examining the joint associations, the all-cause mortality risk of SRVI was higher for those who reported no PA than for those who reported weekly hours of PA. We found a large, positive departure from additivity in adults aged <60 years, whereas the departure from additivity was small for the other age groups.

CONCLUSIONS

Adults with SRVI reporting no PA were associated with an increased all-cause mortality risk. The associations attenuated with age.

The effect of physical activity on mental health among adolescents with and without self-reported visual impairment: The Young-HUNT Study, Norway

The purpose was to study the effect of physical activity (PA) on mental health according to self-reported vision categories among adolescents. The study was conducted in Nord-Trøndelag, Norway, during the period 1995–1997, with a follow-up 4 years later. Self-reported measurements were used to assess PA and vision at baseline, and mental health problems and well-being at follow-up. The main linear regression analyses included 1417 adolescents between the age of 12 and 17 years, of which 46 had reported visual impairment. Among those reporting no impairment, conducting <1 day per week of PA was significantly associated with having lower levels of well-being at follow-up compared to those conducting ⩾1 day of PA. Among those reporting visual impairment, the mental health benefits of conducting weekly PA compared with conducting non-weekly PA were observed only among those who were more emotionally unstable or introvert at baseline. In conclusion, further longitudinal studies are warranted to examine whether the mental health responses of PA may be dependent on the adolescent’s vision status.

Personality, physical activity, and symptoms of anxiety and depression: the HUNT study

PURPOSE

To analyze the association between physical activity (PA), symptoms of depression and anxiety, and personality traits.

METHODS

Cross-sectional study from a Norwegian population-based survey conducted in the period 2006-2008. The sample consisted of a total of 38,743 subjects aged ≥ 19 years, 56.1 % women and 43.9 % men. Demographic variables, PA, depression and anxiety (The Hospital Anxiety and Depression Scale), and personality (Eysenck Personality Questionnaire) were assessed by self-reporting measurements.

RESULTS

Individuals who reported moderate and high PA had significantly lower scores on depression and anxiety compared with less physically active individuals (p < 0.05). Significantly lower risk of HADS-defined depression and anxiety was associated with frequency, duration, and intensity of activity among women (p < 0.05), and significantly lower risk of HADS-defined depression was associated with frequency, duration, and intensity of activity among men (p < 0.05). There was a significant linear trend between extroversion and levels of PA (p < 0.01) and between neuroticism and PA (p < 0.01).

CONCLUSIONS

Subjects reporting regular leisure-time PA were less likely to report symptoms of HADS-defined depression and anxiety. Personality may be an underlying factor in explaining this association.
