The Hoarding Rating Scale-Self-Report (HRS-SR) is a five-item scale that assesses the symptoms of hoarding. These symptoms include excessive acquisition, difficulty in discarding, and excessive clutter that causes distress. We conducted three studies to examine the factor structure, reliability, and validity of the Japanese version of the HRS-SR (HRS-SR-J). Study 1 examined its reliability; 193 college students and 320 adolescents and adults completed the HRS-SR-J and, of the college students, 32 took it again 2 weeks later. Study 2 aimed to confirm that its scores in a sample of 210 adolescents and adults are independent of social desirability. Study 3 aimed to validate the HRS-SR-J in the aspects of convergent and discriminant validity in a sample of 550 adults. The HRS-SR-J showed good internal consistency and 2-week test-retest reliability. Based on the nonsignificant correlations between the HRS-SR-J and social desirability, the HRS-SR-J was not strongly affected by social desirability. In addition, it also had a good convergent validity with the Japanese version of the Saving Inventory-Revised (SI-R-J) and the hoarding subscale of the Obsessive-Compulsive Inventory, while having a significantly weaker correlation with the five subscales of the Obsessive-Compulsive Inventory, except for the hoarding subscale. In addition, the strength of the correlation between the HRS-SR-J and the Japanese version of the Patient Health Questionnaire-9 and that between the HRS-SR-J and the Generalized Anxiety Disorder-7 were significantly weaker than the correlation between the HRS-SR-J and the SI-R-J. These results demonstrate that the HRS-SR-J has good convergent and discriminant validity. The HRS-SR-J is a notable self-report scale for examining the severity of hoarding symptoms.

Ononis species are used for their laxative, diuretic, analgesic, anti-inflammatory, antiviral, cytotoxic and antifungal effects as well as against skin diseases for wound healing activity. In the light of this information n-hexane, ethylacetate and methanol extracts prepared from Ononis spinosa L. subsp. leiosperma (Boiss.) Sirj., Ononis variegata L., Ononis viscosa L. subsp. brevifolia (DC) Nym. and Ononis natrix L. subsp. natrix L. were tested for their wound healing, anti-inflammatory and antioxidant activities. Linear incision and circular excision wound models and hydroxypyroline estimation assay were used for the wound healing activity. For the assessment of chronic inflammation FCA-induced arthritis and for acute inflammation carrageenan-induced hind paw edema, TPA-induced ear edema and acetic acid-induced increase in capillary permeability tests were conducted. 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, 2,2-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) scavenging activity assay, reducing power assay and hydroxyl radical (OH - ) scavenging assay were used for determining antioxidant activities of the extracts. Results showed that O. spinosa subsp. leiosperma roots ethyl acetate extract exhibited remarkable wound healing activity with the 42.6% tensile strength value on the linear incision wound model and 60.1% reduction of the wound area at the day 12 on the circular excision wound model. Hydroxyproline content of the tissue treated by O. spinosa subsp. leiosperma roots ethyl acetate extract was found to be 41.3μg/mg. Acetic acid induced increase in capillary permeability test results revealed that O. spinosa subsp. leiosperma roots ethyl acetate extract and O. spinosa subsp. leiosperma roots methanol extract inhibited inflammation by 40.4% and 35.4% values respectively. O. spinosa subsp. leiosperma roots ethyl acetate extract showed 21.2-27.2% inhibition in carrageenan-induced hind paw edema test while did not posses activity
