In persons with an intellectual developmental disorder, obsessive-compulsive disorder (OCD) and autism spectrum disorder (ASD) are often difficult to differentiate, particularly when patients present major communication difficulties and low accessibility to subjective symptoms and clinicians are poorly trained in the specific psychopathological phenomenology. OCD and ASD share some important symptoms such as repetitiveness of behaviours, low flexibility to contextual variations or a narrow range of interests. The purpose of this study is to identify and describe symptomatological specificities, including how they manifest at behavioural level.

The present study is a retrospective case series study (n = 3) focusing on in-depth assessment, detection and comprehension of symptomatological specificities as well as on the direct observation of behavioural symptoms.

Some symptoms such as signs of sudden autonomous nervous system activation or behavioural equivalents of obsessive thoughts are crucial in achieving an effective differential or comorbidity diagnosis. These symptoms can be identified through a multidisciplinary and comprehensive evaluation, integrating present clinical and test findings with a thorough developmental and medical history. Symptoms should also be interpreted in the light of antecedent, contextual and personal factors.

Differential diagnosis between OCD and ASD in persons with major cognitive and communication issues is a rather neglected research area, although it has significant implications for treatment planning and implementation.

In psychiatry the concept of quality of life (QoL) has gradually acquired importance and interest, becoming a valuable outcome for many clinical trials. In pharmacological research on Autism Spectrum Disorders (ASD), most used outcome measures rely on the effect on behavioural symptoms and functioning impairment, while QoL has rarely been considered. The purpose of this paper is to provide a systematic mapping of the literature on QoL as a new outcome measure in psychopharmacological research for adults with ASD.

The authors reviewed the international literature on the basis of the following questions: did pharmacological interventions on ASD include QoL as an outcome measure? If yes, how and to what extent? What consideration was given to generic (whole‐person) QoL?

The literature mapping shows an extreme lack of studies including QoL as an outcome measure. The few contributions present in the literature show significant conceptual and methodological limits. The literature does not allow any comparison of effectiveness between classes of drugs or single compounds with respect to QoL.

The present mapping is the first contribution of literature reviewing on the application of QoL to pharmacological treatments of any kind for ASD. Although the international scientific community shows increasing interest on QoL and other person‐centred measures in psychopharmacological practice, in respect to ASD considerable research efforts are needed to make these measures applicable and their usefulness actually proved.

Though the very high prevalence of psychiatric disorders (PD) in people with intellectual disability (PwID), the impact of these disorders on adaptive functioning has been minimally investigated. The few contributions present in the literature focussed on children, adolescents, and individual with autism spectrum disorders (ASD). There are no studies concerning the evaluation of any kind of impact on individual skills. Comparison studies between PD and organic disorders, including neurological disorders (ND), was also underexplored. The purpose of this paper is to assess the impact of the presence of a PD on the adaptive functioning of adults with intellectual disability (ID).

In total, 107 adults with ID living in residential facilities or attending day care centers in Tuscany were consecutively assessed with the Psychiatric Instrument for the Intellectually Disabled Adult (SPAID-G), the Diagnostic Manual-Intellectual Disability (DM-ID) criteria, and the Vineland Adaptive Behavior Scales (VABS). The scores were statistically compared and results were controlled for level of ID and other background variables.

The presence of a PD resulted to have a significant negative impact on individual adaptive skills. Participants with PD scored significantly lower than those without PD in communication and socialization areas of VABS. Participants with ND scored significantly lower than people without ND in daily living and motor skills. The average scores of participants with only PD and those of participants with PD and ND showed no significant differences. Significant differences were found between participants with only ND and participants with ND and PD in the interpersonal relationship subscale.

As far as the best knowledge, this is the first study on the evaluation of the impact of any kind of PD on the abilities of PwID. This paper suggests that the presence of a PD seems to have a relevant negative impact on functioning of PwID higher than that of ND, particularly in communication and socialization skills.

Diagnosing psychiatric disorders (PD) in adults with Intellectual Disability (ID) presents several issues and need specific skills and tools. The purpose of this paper is to provide a detailed description of the current status of art through a systematic mapping of the literature.

The authors reviewed the international literature on the basis of the following questions: what are the issues in the psychiatric diagnostic process for adults with ID? What methods and procedures have been used for psychiatric assessment in ID? To date, is it possible to identify some most effective procedures?

The analysis of the literature indicates that main issues of the psychiatric diagnostic process in adults with ID are the following: identification of psychiatric symptoms, behavioural equivalents, diagnostic criteria, setting, source of information, screening, and diagnostic tools. The evidence base is only emerging and although many relevant achievements have been reached in the last two decades, no definitive guideline has been produced. Most recent acquisition also allowed to identify some assessment procedures that are currently considered the most effective. Individualised assessment remains the best way to meet the needs of this heterogeneous and variable patient group.

This paper offers a comprehensive and updated description of current achievements and issues towards the assessment of PD in people with ID.

The debate as to whether intellectual disability (ID) should be conceptualized as a health condition or as a disability has intensified as the revision of World Health Organization’s (WHO’s) International Classification of Diseases (ICD) is being finalized. Defining ID as a health condition is central to retaining it in ICD, with significant implications for health policy and access to health services. The purpose of this paper is to include some reflections on the consensus document produced by the first WHO Working Group on the Classification of MR (WHO WG-MR) and on the process that was followed to realize it. The consensus report was the basis for the development of official recommendations sent to the WHO Advisory Group for ICD-11.

A mixed qualitative approach was followed in a series of meetings leading to the final consensus report submitted to the WHO Advisory group. These recommendations combined prior expert knowledge with available evidence; a nominal approach was followed throughout with face-to-face conferences.

The WG recommended a synonym set (“synset”) ontological approach to the conceptualisation of this health condition underlying a clinical rationale for its diagnosis. It proposed replacing MR with Intellectual Developmental Disorders (IDD) in ICD-11, defined as “a group of developmental conditions characterized by a significant impairment of cognitive functions, which are associated with limitations of learning, adaptive behaviour and skills”. The WG further advised that IDD be included under the parent category of neurodevelopmental disorders, that current distinctions (mild, moderate, severe and profound) be continued as severity qualifiers, and that problem behaviours removed from its core classification structure and instead described as associated features.

Within the ID/IDD synset two different names combine distinct aspects under a single construct that describes its clinical as well as social, educational and policy utilities. The single construct incorporates IDD as a clinical meta-syndrome, and ID as its functioning and disability counterpart. IDD and ID are not synonymous or mirror concepts as they have different scientific, social and policy applications. New diagnostic criteria for IDD should be based on a developmental approach, which accounts for the complex causal factors known to impact the acquisition of specific cognitive abilities and adaptive behaviours. The paper focuses on a new clinical framework for the diagnosis of IDD that also includes and complements the existing social, educational and policy components inherent in ID.

This paper aims to investigate the effect of the nature of ownership and board characteristics on the investment choices in joint ventures (JVs) from the dimensional point of view, controlling for the effect of JV type and other components of intellectual capital.

The authors study a sample of Italian, Spanish, German and French nonfinancial listed firms over the 2010–2018 period, controlling for the fixed effects of the company's sector of operation and the year. The authors also analyze the effect of family control and influence on JV investment size, taking into consideration certain board characteristics, the type of JV, human capital efficiency, structural capital efficiency and capital employed efficiency while also controlling for a firm's profitability and size. To test the hypotheses, GLS panel data was used.

The results indicate that the size of the investment in JVs is smaller for family firms than for nonfamily businesses. The presence of CEO duality has an opposing effect on the size of the investment in joint ventures as it has a lowering effect in family businesses while it exerts an amplifier influence in nonfamily businesses. Moreover, the type of joint venture has a significant effect for family firms: the choice of a link joint venture reduces the size of the investment. The authors find that human capital efficiency increases JV investment size for all firms.

This study is the first to analyze the effect of the main dimension of socioemotional wealth – family control and influence – on a firm's JV investment size. It controls for the effect of JV type – link or scale – and the interplay of the other IC components.

The aim of this paper is to examine the effect of structural and demographic board diversity as well as board tenure on family firms' environmental performance, by analyzing the differences between family and non-family businesses and within family firms.

Tobit regressions are applied to investigate the effect of independent directors, CEO non-duality, board gender diversity and board tenure on environmental performance. The study also controls for other board and firm characteristics, as well as for time, industry and country-fixed effects. In doing so, the authors rely on a sample of non-financial listed firms from France, Germany, Italy, Spain and Portugal over the period 2014–2021.

The authors find that women on the board positively influence environmental performance and this effect is significant only in family firms, although board tenure negatively moderates the relationship. Board independence significantly affects environmental performance only in non-family firms. A strong presence of family directors has a negative effect on family firms' environmental performance, especially when directors' turnover is low.

This paper examines the unexplored relationship between structural board diversity and environmental performance in family companies. This study provides empirical evidence on the association between gender diversity and family firms' environmental performance focusing for the first time on a European setting. Moreover, this study provides evidence of a different effect of board tenure in family and non-family businesses.

Hempseed oil is a valuable emerging food product with recognized health positivity due to its composition. The paper aims to propose a multi-methodological chemical profiling of nine organic hempseed oil samples (different brands and prices) from the retail market, followed by multivariate data analysis.

Fatty acids, tocopherols, squalene, total carotenoids content, phenolic compounds, total phenolic content and anti-radical activity (DPPH• and ABTS•+ assays) were determined through chromatographic and spectrophotometric techniques. Multivariate (explorative and discriminant) analyses were applied to the profiling results to classify samples according to information claimed on the label, i.e. geographical origin (EU vs. non-EU), extraction procedure (cold-pressed vs. not cold-pressed) and price (lower or higher than 10 € per 250 mL).

The chemical analysis confirmed the 3 to 1 ?-6:?-3 ratio and the excellent content in antioxidant species. However, no specific trend of results can be stressed. PCA (after variables selection) highlighted a natural grouping of samples, so three discriminant analyses were performed: kNN, Naïve Bayes and LDA. The best classification efficiency was reached for the extraction procedure verification (93–100% correct classification), followed by geographical origin (83–94%) and prices (81.6–90%).

The integrated approach of chemical profiling coupled with multivariate analyses allowed the assessment of label information of the analyzed organic hempseed oil samples, despite the wide heterogeneity of the selected samples.
