Hi Manal, why don't you try the Centrality of Religiosity Scale? Article The Centrality of Religiosity Scale (CRS)

Thank you so much for your reply and cooperation. what I need is instrument developed to assess Muslim spirituality not religiosity based on Islamic perspective.

Thank you.

Appreciated.

If you do not mind to contact prof. Arndt Bussing for the same.

Google Arndt Bussing.

Thank you so much.

Arndt Bussing' scale developed based on western perspective. I need scale developed based on Islamic perspective.

Hi, I could recommend the Spiritual Well-Being Scale (SWBS) by Prof. Paloutzian, which was already used in arabic version. Moreover, we have published its shortened adjusted 7-item version for adolescents, which has better psychometric properties.

Thank you so much.

Here is the reference on a shorter version, however, you would still need the permission also from Prof. Paloutzian:

Malinakova, K., Kopcakova, J., Kolarcik, P., Geckova, A. M., Solcova, I. P., Husek, V., ... & van Dijk, J. P. (2017). The Spiritual Well-Being Scale: Psychometric evaluation of the shortened version in Czech adolescents. Journal of religion and health, 56(2), 697-705.

what about do you ask me?

I believe Maureen Miner recently produced and Islamic Attachment to God scale.

Thank you so much.
