Background: Projective instruments have historically been used to explore unconscious dynamics and personality traits in children and adolescents. However, concerns about their psychometric properties have led to ongoing debates in clinical psychology. This review aims to critically reassess the use of construction projective techniques in clinical settings for individuals aged 4 to 18 years, also examining the available psychometric data reported in recent scientific literature, excluding the Rorschach Test due to its extensive coverage in existing literature. Methods: A systematic review was conducted following PRISMA guidelines. PubMed, Psychoanalytic Electronic Publishing (PEP), and the Cochrane Library were searched for studies published between 2010 and 2024. Inclusion criteria encompassed studies focusing on construction projective techniques administered to clinical and non-clinical samples aged 4 to 18 years. Results: From an initial pool of 641 articles, 25 met the inclusion criteria. These studies indicate that construction projective techniques remain valuable in accessing children’s and adolescents’ inner worlds, particularly in diagnostic and therapeutic contexts. However, 13 of the 25 analyzed studies lack detailed psychometric evaluations, and the overall methodological quality was medium-low (4.4/9). Recent adaptations of these techniques show promise in increasing their applicability and relevance. Conclusions: Constructive projective tests continue to offer unique insights into the psychological functioning of young individuals. While not definitive diagnostic tools, they serve as effective supplements in clinical assessments and therapeutic interventions when applied with awareness of their limitations.

Benign paroxysmal positional vertigo (BPPV) usually has a favorable course, although it is possible to observe BPPV with a high recurrence rate. Previous studies suggested that vitamin D deficiency might affect BPPV recurrences, and oxidative stress might play a complementary role in BPPV pathogenesis. This multicentric trial aimed to evaluate the effectiveness of oral nutritional supplementation with a compound of alpha-lipoic acid, Carnosine, and Zinc (LICA® (Difass International, Coriano (RN), Italy)), vitamins of group B and vitamin D in preventing BPPV recurrences. A total of 128 patients with high recurrence-BPPV were randomized in three arms: Arm 1 consisted of subjects with “insufficient” or “deficient” vitamin D blood levels, treated with daily oral supplementation of LICA®, vitamins of group B and vitamin D3 (800 UI), Arm 2 included BPPV subjects with “sufficient” vitamin D who did not receive any nutritional support, and Arm 3 included subjects with a “sufficient” serum concentration of vitamin D who received supplementation with a compound of LICA® and Curcumin. After six months of follow-up, a significant reduction of BPPV relapses compared to the baseline was found only in Arm 1 (−2.32, 95% CI: 3.41–1.62, p-value < 0.0001). Study results suggested that oral nutritional supplementation with vitamin D3 plus antioxidants can prevent relapses in patients suffering from high recurrence-BPPV.
