Young children with intellectual disabilities and their mathematical attainments: Do parents' attitudes toward mathematics, home numeracy, and literacy practices matter?

This study explored potential factors of numeracy acquisition in young children with intellectual disabilities (IDs). Those factors are determined to assess parents' academic expectations and home practices that they use with their children daily. The sample consisted of 187 Greek-speaking couples, comprising a total number of 374 parents. All of them had a child with mild IDs aged between 4 and 7 years old. Since Greece is placed among European countries with the lowest median disposable income it is significant to assess the potential effects of each family's socioeconomic status. We employed structural equation modeling to identify potential factors affecting a child's with IDs numeracy outcomes. Analysis of moments structures (AMOS) revealed that there is a good fit for the suggested second-order structural equation model. Results are discussed regarding their practical implications.

The role of marital satisfaction and social activities on parents' self-perception: evidence from Greek families of children with and without disabilities.

The purpose of this study is to explore the association between marital satisfaction and social activities with parents' self-perception. Self-perception included parents' sense of self and their attitudes and beliefs about who they are as individuals and as parents. Three hundred and twenty-seven parents, having either a child with (D1-target group) or without (D2-control group) a disability, were enrolled in the study. We hypothesized that self-perception of parents in the target group would be lower in all measures. We also hypothesized that low self-perception will correlate with parents' marital satisfaction and social activities. We found that parents of a child with disabilities reported significantly lower levels in all domains (self-perception, marital satisfaction and social activities) than parents of children without disabilities. Moreover, multigroup analyses confirmed that the structural paths between self-perception, marital satisfaction and social activities do not differ between D1 and D2 parents (χ2(127, N = 327) = 134.62, p>.05, CFI = 1.00 ≥ 0.90, RMSEA=.063 ≤ .080, SRMR = 0.054 < 0.08, TLI = 1.000 > 0.95). Results are discussed in terms of children's educational placement and their implications on children with and without disabilities unobstructed co-development and co-existence with their parents in the family context.

Attitudes towards people with disabilities across different healthcare undergraduate students: A cluster analysis approach.

BACKGROUND AND PURPOSE: Negative attitudes towards disability amongst healthcare professionals endanger social inclusion of people with disabilities (PwD). This study aimed to investigate the attitude of undergraduate healthcare students of various disciplines towards PwD, including specific aspects of their attitude. METHODS: We assessed the attitudes of university students, including physiotherapy, speech therapy, nursing, social work and medical students, through the Greek Interaction with Disabled Person Scale (IDPS) in a survey. Data were analysed using a two-step clustering technique. RESULTS: Four hundred-eighty undergraduate healthcare students (21.4 ± 5.3 years-old; 135 males, 345 females) were recruited. Two-step cluster analysis identified three homogenous subgroups labelled Least positive attitude (42.3%), Moderately positive attitude (26.9%), and Most positive attitude (30.8%) groups. Τhe main differences in healthcare students' attitudes between the three distinct groups appeared to be in feelings of sympathy, fear and susceptibility towards disability, suggesting that these aspects of attitude needed to be primarily addressed. Results also revealed that females, being in higher semester/year of studies, having completed a clinical module with PwD and having frequent contact with PwD were related to more positive attitudes. CONCLUSION: Taking into account that the majority of the healthcare students' sample yielded least and moderately positive attitudes, towards PwD, further actions should be taken for promoting more positive attitudes towards disability. A social model in teaching to increase student's awareness of PwD and skills to work with these people, having PwD themselves teaching such modules, focussing on positive experiences and reminding the students of the benefits of having positive attitudes towards PwD, as well as promoting ways to increase the contact of healthcare students with PwD (such as teaching in co-operation with organisations of PwD or finding alternative clinical placements with PwD), can be beneficial in promoting more positive attitudes towards disability.

Factor structure of early numeracy: evaluation of a measurement model in greek-speaking children with intellectual disabilities.

Exploring the individual differences of the longitudinal growth of early numeracy (EN) in young children with Intellectual disabilities (IDs) prerequires the critical stage of exploring and validating the potential factor structure. Despite the fact that Relational Skills (RS), Counting Skills (CS) and Operations (O) are expected to constitute distinct domains of EN, there is not sufficient evidence to support either the above position or the position that they are different means of assessing a general-informal numeracy skill construct. This study was designed to shed light in the field through the evaluation of a measurement model describing the structure of RS, CS and O domains of EN and their interrelation. The sample included N = 155 children with IDs, enrolled in special school classes, mentally aged between 5;02 (y;m) and 6;10 (M = 5.11, SD = 0.974). Confirmatory Factor Analysis indicated a "good fit" of the two-factor model (RS, CS + O) of EN in ID (RMSEA=.029 < 0.08, CFI = 0.98 ≥ 0.90 and SRMR = 0.000 < 0.08). No measurement invariance across gender was reported for the proposed two-factor model of EN. The nested EN models validated full measurement invariance across gender. Finally, educational implications are discussed.

What are the optimum training parameters of progressive resistance exercise for changes in muscle function, activity and participation in people with cerebral palsy? A systematic review and meta-regression.

OBJECTIVES: To explore the effect of progressive resistance exercise (PRE) on impairment, activity and participation of people with cerebral palsy (CP). Also, to determine which programme parameters provide the most beneficial effects. DATA SOURCES: Electronic databases searched from the earliest available time. ELIGIBILITY CRITERIA: Randomised controlled trials (RCTs) implementing PRE as an intervention in people with cerebral palsy were included. STUDIES APPRAISAL & SYNTHESIS METHODS: Methodological quality of trials was assessed with the PEDro scale. Meta-analysis and meta-regression were completed. RESULTS: We included 20 reports of 16 RCTs (n = 504 participants). Results demonstrated low certainty evidence that PRE improved muscle strength (pooled standardised mean difference (SMD)= 0.59 (95%CI: 0.16-1.01; I²=70%). This increase in muscle strength was maintained an average of 11 weeks after training stopped. Τhere was also moderate certainty evidence that it is inconclusive whether PRE has a small effect on gross motor function (SMD= 0.14 (95%CI: -0.09 to 0.36; I²=0%) or participation (SMD= 0.26 (95%CIs: -0.02 to 0.54; I²=0%). When PRE was compared with other therapy there were no between-group differences. Meta-regression demonstrated no effect of PRE intensity or training volume (frequency x total duration) on muscle strength (p > 0.5). No serious adverse events were reported. There is lack of evidence of the effectiveness of PRE in adults and non-ambulatory people with CP. CONCLUSIONS: PRE is safe and increases muscle strength in young people with CP, which is maintained after training stops. The increase in muscle strength is unrelated to the PRE intensity or dose.

Early numeracy profiles in young children with intellectual disabilities: The role of cognitive functions.

Exploring individual differences and looking beyond averaged parameters of early numeracy in young children with mild intellectual disabilities has become an area of interest to many researchers worldwide. This study aimed to identify the different profiles of early numeracy skills in young children with mild intellectual disabilities. For this purpose, we assessed early numeracy through Utrecht early numeracy test and learning aptitude through Detroit Test, in a sample of 135 children diagnosed with intellectual disabilities. The mean of their mental age was 5:09 (years:months). Two-step cluster analysis identified four homogenous groups of children with distinct early numeracy profiles as follows:C1 were fluent in relational and numerical skills up to 20, C2 were fluent in relational skills and numerical skills up to 10, C3 had basic knowledge of relational skills and inconsistent numerical skills up to 10 and C4 had inconsistent relational skills and numerical skills. Results are discussed with reference to their educational implications.

The Interaction with Disabled Persons Scale: evidencing construct validity with factor analysis and measurement invariance in Greek-speaking healthcare students.

PURPOSE: To explore the construct validity and reliability of the Greek version of the Interaction with Disabled Persons Scale (IDPS) amongst healthcare students. METHODS: Greek IDPS factors were extracted and confirmed by Analysis of Moment Structures. Measurement invariance for the group of students completing a clinical module with people with disabilities was also evaluated. The scale was distributed twice, 3 weeks apart (test-retest reliability) to sample. Greek IDPS scores amongst students with frequent contact with people with disabilities were compared with those with infrequent contact (discriminant validity). RESULTS: 327 healthcare students (21.25 ± 4.3 years, 118 males) participated. Exploratory factor analysis extracted 6 factors explaining 55.66% of total variance. Confirmatory factor analysis showed a good fit of the model (AGFI = 0.95 > 0.90, RMSEA = 0.07 < 0.08, CFI = 0.95 ≥ 0.90, SRMR = 0.00 < 0.08). An adequate fit for the students completing a clinical practice module was observed. The scale's test-retest reliability and internal consistency were excellent; ICC(2,1)=0.86 (CIs:0.82-0.89) and Cronbach's α = 0.87, respectively. Statistically significant differences between the two student groups were yielded; students with frequent contact with people with disabilities had lower scores (mean difference: -4.5; CI: -6.6 to -2.4), suggesting that they were significantly more comfortable with people with disabilities than the students with infrequent contact. CONCLUSION: The Greek IDPS provided sufficient validity and reliability evidence for evaluating healthcare students' perceptions and attitudes towards people with disabilities.IMPLICATIONS FOR REHABILITATIONThe Greek IDPS demonstrated sufficient validity and reliability evidence to assess the Greek-speaking healthcare students' perceptions and attitudes towards people with disabilitiesCompleting a clinical module working with people with disabilities is not enough to produce adequately positive attitudes in Greek-speaking undergraduate healthcare students. Therefore, faculties need to organize further actions, such as lectures by people with disabilities, students' role play, and discussions or events in co-operation with people with disabilities.

The Interaction with Disabled Persons Scale: translation and cross-cultural validation into Greek.

AIM: Cross-cultural adaptation of the Interaction with Disabled Persons Scale (IDPS) into Greek. METHODS: The IDPS was forward and back-translated by two bilingual physiotherapists and a Greek-English translator, respectively. Greek-speaking health professionals provided modifications in order to develop the final version of the Scale. Health professionals filled in the Greek version of the IDPS and the Caring Behaviors Inventory (for criterion validity). The factors of the Greek IDPS were extracted as well. After 8-10 days, the scale was re-distributed to the same health professionals (test-retest reliability) and to a general population sample (discriminant validity). RESULTS: Eighty-seven health professionals (36 ± 7.6 years) and 80 general population participants (44 ± 11.6 years) participated. There was a trend for the Greek IDPS variability to predict the variability of the Caring Behaviors Inventory (r2 = 0.05; p = 0.054), but the coefficient of determination was low. An explanatory factor analysis extracted four factors explaining 66.66% of the total variance, confirmed by reliability analysis. The health care professionals had a significantly lower score than the general population in the Greek IDPS (mean difference: -11.0; confidence interval: -7.3 to -14.7), indicating familiarisation with the management of people with disability. The scale reliability and internal consistency were excellent; ICC(2,1) = 0.92 (confidence interval: 0.87-0.95) and Cronbach's α = 0.96 respectively. No ceiling or floor effects were observed. CONCLUSIONS: Substantial validity and reliability were observed for the Greek IDPS to assess Greek health professionals' attitudes towards people with disabilities.Implications for rehabilitationThe Greek IDPS version was shown to be comprehensible, and has demonstrated a sufficient amount of validity and reliability for assessing the perceptions and attitudes of Greek health professionals towards people with disabilities.Exploring attitudes towards people with disabilities in Greek-speaking populations, especially health professionals, with a scale such as the Greek IDPS is very important as it can help promote positive changes in approaches towards disability.
