I usually use the DASS to assess depression, anxiety, and stress (Lovibond & Lovibond). It is well-validated and also has a 21 item version which works well.

A quick literature review will show you that the GHQ-12 and the DASS-21 are two of the most widely used measures of mental health. Regarding the DASS-21, many authors have argued that only a total score (instead of the original depression, anxiety, and stress subscales) should be calculated.

COVID-19 Pandemic Mental Health Questionnaire (CoPaQ): Rek, S., Freeman, D., Reinhard, M., Keeser, D., & Padberg, F. (2020).The Covid-19 Pandemic Mental Health Questionnaire (CoPaQ): Introducing a comprehensive measure of the psychosocial impact of the coronavirus crisis.

Description: The COVID-19 Pandemic Mental Health Questionnaire (CoPaQ) is a newly developed and highly comprehensive self-report measure of personal and social consequences of the COVID-19-pandemic with an application scope world-wide. The questionnaire covers a wide range of areas of interest affected by the COVID-19 pandemic; that is, COVID-19 infection status, socio-demographic background, and the impact on risk perception, affect, thoughts, behaviour, mental health, media usage, institutional trust and social cohesion. It takes around 20 minutes to complete. We apply the CoPaQ questionnaire concurrently with well validated questionnaires assessing the following domains: depression, anxiety, stress, paranoia, quality of life, rumination, loneliness, size of the social network, childhood trauma, and resilience.

We suggest three batteries of different duration.

• The long version (max. 15 min) comprises measures of anxiety, depression and stress (DASS-21), paranoia (R-GPTS), quality of life (WHO-5), rumination (PTQ), loneliness (UCLA Loneliness Scale), size of social network (SNI), childhood trauma (CTQ-SF), and resilience (BRS). • The medium version (max. 10 min) includes the DASS-21, R-GPTS, WHO-5, UCLA Loneliness Scale, and SNI. • The short version (max. 5 min) contains the DASS-21, R-GPTS, and WHO-5. The CoPaQ was developed in a collaborative effort between the Ludwig Maximilian University Munich (GER) and the University of Oxford (UK). We appreciate translation efforts into other languages and encourage its use, but appreciate referencing our work via this OSF repository reference (DOI 10.17605/OSF.IO/3EVN9). The questionnaire batteries are available in English and German language (feel free to contact [email protected]).

The MMPI-5, in its latest version ... perhaps the most complete and widely used Inventory in the world

CORE

I think MMPI is more designed to measure stable traits/personality, and might not be suitable to detect reactions to the pandemic. Also, it is very time consuming. SDQ (Goodman; sdqinfo.org) has an adult version, BAI and BDI (Beck) are specifically addressing anxiety and depression symptoms

In any case, I would recommend to find an instrument that is used in your country, and validated for that cultural and linguistic context, unless you plan to do that kind of validation yourself.

I think the Mental Health Inventory (MHI) effectively captures important aspects of well-being you are trying to measure. This instrument provides an assessment of several domains of mental health including anxiety, depression, behavioral control, positive affect, and general distress. Another tool to measure overall well-being would have to be the PERMA-H Profiler. This tool measures the five core elements of well-being; namely positive emotions, engagement, meaningfulness, relationships, and accomplishment

The State-Trait Anxiety Inventory (STAI Y-1 and Y-2; (Spielberger et al., 1983) gives a quantitative measurement of cognitive anxiety. Focus on STAI Y-2 as this measures trait levels of anxiety (the general anxiety level). This gives a quick measurement as there are only 20 questions to answer and indicates on a likert scale if the individual has low, medium or high anxiety levels. Good luck

Indeed ... but, as their own names indicate, they only evaluate two psychopathological variables: Anxiety (BAI) and Depression (BDI), which are poor and scarce indicators of MENTAL HEALTH, WHICH IS WHY THEY ARE ASKED FOR IN THIS QUESTION. On the other hand, the "STAI" only evaluate Anxiety -Trait and State-; If what you want is to measure and evaluate MENTAL HEALTH AS SUCH, A QUESTIONNAIRE OR SYSTEMIC INVENTORY IS INDEFECTIBLY REQUIRED (it is as if to evaluate Physical Health, through an analysis, we only did a blood glucose level, because it is shorter and faster, and NOT A HEMO ANALYSIS AND SYSTEMIC UROANALYSIS !!)

I like MCMI-IV Millon -IV it´s quite completed

The MHC-SF may be useful in this regard.

Ereny Gobrial, perhaps the Warwick-Edinburgh Mental Well-Being Scale might suit your purposes. It is free, freely available, and, in my view, a reliable and valid scale. Useful norms are also provided.

DASS 21 scale.

thank you so much for you all recommending and suggesting the answer to my question.

You are very kind and gentle.Thanks to you.
