Background: A variety of psychosocial factors have been shown to affect the quality of life of families (FQoL). Aim: This study aimed to assess the impact of mother's demographic characteristics, parental stress, illness perceptions about autism spectrum disorder (ASD), coping strategies, ASD severity and time since diagnosis on FQoL during the initial period following diagnosis (≤6 months). Method: Fifty-three mothers of children newly diagnosed with ASD completed the Beach Center Family Quality of Life Scale, the Autism Parenting Stress Index, the Brief Illness Perception Questionnaire and the Brief Coping Orientation to Problems Experienced Inventory. A descriptive analysis was conducted on the demographic characteristics of the family. Eta coefficients and Pearson's analysis were used to determine the associations between the variables and the FQoL dimensions. Hierarchical regression was used to determine whether variables explained a statistically significant family quality of life variance. Results: Pearson's analysis and eta coefficients indicated several correlations. Hierarchical regression analysis showed that higher parental stress related to core autism symptoms was associated with poorer FQoL (95% CI −0.08 to −0.02, P = 0.001), and higher perceived treatment control was associated with better FQoL (95% CI 0.04–0.16, P = 0.001). In addition, stronger perceived personal control was associated with higher physical/material well-being (95% CI 0.01–0.16, P = 0.022) and higher disability-related support (95% CI 0.30–0.61, P = 0.001). Higher family monthly income was associated with better FQoL (95% CI 0.08–0.027, P = 0.000), whereas marital status (divorced mother) was correlated with poorer FQoL (95% CI −0.68 to −0.16, P = 0.002). Conclusions: Interventions should emphasise managing the disorder's characteristics and implementing psychoeducational and supportive programmes for parents, immediately after the diagnosis, to enhance FQoL.

Multiple sclerosis (MS) is a chronic inflammatory and demyelinating autoimmune disease. MS patients deal with motor and sensory impairments, visual disabilities, cognitive disorders, and speech and language deficits. The study aimed to record, enhance, update, and delve into our present comprehension of speech deficits observed in patients with MS and the methodology (assessment tools) studies followed. The method used was a search of the literature through the databases for May 2015 until June 2022. The reviewed studies offer insight into speech impairments most exhibited by MS patients. Patients with MS face numerous communication changes concerning the phonation system (changes observed concerning speech rate, long pause duration) and lower volume. Moreover, the articulation system was affected by the lack of muscle synchronization and inaccurate pronunciations, mainly of vowels. Finally, there are changes regarding prosody (MS patients exhibited monotonous speech). Findings indicated that MS patients experience communication changes across various domains. Based on the reviewed studies, we concluded that the speech system of MS patients is impaired to some extent, and the patients face many changes that impact their conversational ability and the production of slower and inaccurate speech. These changes can affect MS patients’ quality of life.

Background: Caregivers of children with autism spectrum disorder (ASD) are sensitive to the internalisation of the stigma, known as affiliate stigma, resulting in reduced self-esteem, isolation and poor psychological well-being.Aims: This study aims to validate the Greek version of the Affiliate Stigma Scale (ASS) among mothers of children with ASD.Method: The translated version of ASS in Greek was administered to 53 mothers of children newly diagnosed with ASD in two time periods: 1–6 months from diagnosis (time point 1) and 12 months from the initial assessment (time point 2). The control group consisted of 62 mothers of typically developing children.Results: The ASS total mean score revealed a moderate level of stigma to the ASD group in both assessments. The reliability measures by item showed a satisfactory composite reliability (affective 0.828, cognitive 0.833, behaviour 0.857). Cronbach's alpha revealed that the estimated internal consistency was excellent (α= 0.888), and it found a high positive item-total correlation. Receiver operating characteristic analysis results indicated a statistically significant positive discrimination (area under the curve 0.849,P= 0.000) between the groups. The cut-off point was 31.00, with a sensitivity of 0.849 and a 1 – sensitivity of 0.258.Conclusions: The proposed version of the ASS has good psychometric properties and is valid and reliable for measuring affiliate stigma among caregivers of children with ASD in Greece. Health professionals can use it to assess and understand the stigma experienced by caregivers of children with ASD, and design appropriate interventions to reduce their affiliate stigma.

(1) Background: This study aimed to validate the Greek version of the Autism Parenting Stress Index (APSI) among parents of children with ASD. (2) Methods: The translated version was administered to 113 parents (Male: 12, Female: 101, 39.24 years old, SD 6.70, age range, 25–58) of children diagnosed with ASD and 127 parents (Male: 24, Female: 103, 41.08 years old, SD 6.22, age range: 27–56) of typically developing children. (3) Results: Significant differences between the APSI total scores and three domains between groups were observed. Although the initial factor structure could not be replicated, the APSI’s internal consistency was excellent (a = 0.914), with a high positive item–total correlation (0.900–0.917). The APSI’s test–retest reliability was excellent, showing an ICC equal to 0.922 [95%, CI: 0.900–0.940]. The APSI’s total score cut-off point was equal to 12.00 (AUC 0.845, p < 0.001) with a sensitivity of 0.839 and 1-specificity of 0.220. A principal component analysis of the 13 items, using varimax rotations, identified three factors, which explained approximately 45.8% of the overall variance. (4) Conclusions: The Greek version of the APSI exhibited discriminant validity for measuring parents of children with ASD. Greek health professionals can use it to assess the stress experienced by parents of children with ASD.

One of the components of a dementia diagnosis is the assessment of functional abilities. These abilities are measured via screeners, such as the Instrumental Activities of Daily Living (IADL) scale. The IADL scale is a valid tool that has been adapted in many languages. This study aimed to provide a cut-off point and validate the Greek version of the IADL scale in populations with cognitive impairment. IADL data were collected from 132 individuals: 24 PD patients, 24 Parkinson’s disease dementia (PDD) patients, and 24 AD patients. The remaining 60 participants were cognitive healthy adults (CHAs). The CHA group and the PD group served as the cognitively unimpaired group (CUG), while the PDD and AD groups served as the cognitively impaired group (CIG). Additionally, the MMSE, the AMTS, the Clock Drawing Test CDT, the Arizona Battery for Communication Disorders of Dementia (ABCD), the NPI, and the GDS-15 were administered to the participants. Statistically significant differences in the IADL scores were exhibited between all subgroups. The IADL scale showed high internal consistency (Cronbach’s alpha = 0.890). A threshold equal to 6.00 (AUC = 0.888, p < 0.001) was estimated between the CUG and the CIG. Significant positive correlations were observed between IADL and MMSE (r = 0.764, p < 0.001), IADL and AMTS (r = 0.724, p < 0.001), IADL and ABCD (r = 0.702, p < 0.001), and IADL and CDT (r = 0.627, p < 0.001) results. Given the obtained results, the IADL scale is a valid tool for clinical use with high reliability and sensitivity. Also, the IADL scale is a valuable instrument for screening functional abilities associated with cognitive impairment.
